2. Where can I get this FAQ?
This document should be archived at many sites on the Internet, including rtfm.mit.edu -- the archive site for all FAQs. It is also available via
e-mail from the author (wmklein@ix.netcom.com).
An HTML version of the latest FAQ is also available from
http://www.cobolreport.com/faqs/cobolfaq.htm
2.1 Where do I turn if my question isn't answered in this FAQ?
If you have access to the web (but not to Usenet newsgroups), you can go to
http://groups.google.com/
From this page:

Select “Advanced Groups Search”

Fill in the “Find Messages” section with appropriate words

Place “comp.lang.cobol” in the newsgroup field
The chances are that you will find more than enough answers already (and many quite recent) to your question. If you don't find an answer
here, then look at 18. What can/should I post in the COBOL newsgroups?
3. Where can I get a COBOL compiler?
There are many vendors who sell COBOL compilers. Almost all of the mainframe hardware/operating system vendors, also sell a COBOL
compiler for their systems. The following are some of the vendors providing COBOL compilers for systems where they are not the operating
system vendor.
3.1 for DOS, OS/2, or 16-bit Windows?
Acucorp, CA, Fujitsu, Liant, IBM, and Micro Focus all produced compilers for one or more of these DOS environments. Microsoft used to
repackage the Micro Focus compiler under their name, but not any more. It is doubtful that any of these vendors still “actively” sell (market
for commercial use) these products (although Micro Focus does sell a couple of “academic” products for Windows 3.1 and later). It is possible
that you can find “old” copies of some of the other products via eBay or other online auctions of products. However, licensing requirements
may make acquisitions of such copies of questionable validity or legality. Especially if you want to “market” your compiler’s output, I
strongly suggest that you contact the specific compiler vendor for legal issues.
IBM, Micro Focus, and LegacyJ all have had products for OS/2. It is not clear that any of these (even IBM) is “updating” their OS/2
development environments – much less selling them.. Check with the specific vendor for current information.
3.2 for 32-bit Windows?
Micro Focus (formerly MERANT) has development environments for Windows called Net Express and Mainframe Express. A student version
of Net Express is also available from Micro Focus. Fujitsu's compiler also works under Windows. Liant has development systems for
Windows. Computer Associates has Advantage™ CA-Realia® II Workbench.. IBM's VisualAge for COBOL is also available for
Windows/NT. Acucorp's AcuCOBOL-GT also runs under 32-bit Windows.
NOTE: For details on whether each of the following supports 16-bit as well as 32-bit systems and whether or not they work under
Windows/NT, Windows/95, Windows/98, and/or Windows/2000, see the specific vendor’s information.
3.3 for UNIX?
Acucorp, Fujitsu, Liant, and Micro Focus have products available across a large number of UNIX platforms. Some OEMs re-badge and/or reengineer these products for their own systems too.
Liant used to provide LPI COBOL for Sun SPARC with Solaris 2, HP 9000 with HP-UX and Intel-based machines with UNIX SVR4, SVR3,
and SCO. They no longer make this product.
IBM sells its COBOLSet for AIX.
3.4 for Linux?
AcuCOBOL-GT is available for Linux. Also, the iBCS2 code for Linux should mean that it is possible to get some of the i486 COBOL
packages for operating systems such as SCO UNIX to work. Micro Focus provides a development environment for Linux (including
announced – but not yet delivered – plans for a Linux/390 product). PERCobol from LegacyJ also supports Linux, as does RM.
For specific information on each vendor’s Linux support, see their product information below or at their web site.
There is a project (referred to as the “Tiny COBOL” project) working on creating a new Linux compiler. If you are interested in its status (or
better yet helping them), please see:
http://tiny-cobol.sourceforge.net/
3.5 for the Macintosh?
Acucorp produces a COBOL development system for the Mac running A/UX. There are no reports of any current COBOL products targeted at
the standard MAC operating systems.
3.6 for other environments?
Fujitsu COBOL is also available for IBM MVS and Fujitsu MSP.
Ryan McFarland COBOL is also available for OpenVMS.
AcuCOBOL-GT is available on a wide range of environments, including OpenVMS.
Most major vendors have their own COBOL implementation, or have someone else's ported to their platform(s). There are quite a few available
for CP/M and MP/M, and one is even rumored to have been available for the PERQ workstation.
4. Is there a free COBOL compiler?
There are two current/ongoing projects to produce an "open source" and/or GNU compiler. For one, see the project “COBOL for GCC”. This
site also includes a status on various other “open source” projects.
http://cobolforgcc.sourceforge.net/
Also, see the “Tiny COBOL project” at:
http://tiny-cobol.sourceforge.net/
Also several books in the booklists come with a COBOL compiler. See section 10 for details.
For some other possibilities, see:
http://www.thefreecountry.com/developercity/cobol.html
4.1 for DOS, Windows or OS/2.
There is a freely available COBOL compiler for DOS. It can be found on many archive sites, named COBOL650.ZIP. You also need
DPATH30.ZIP. Have a read through Section 8 before you start.
Bob Wolfe has made the compiler available at the Flexus FTP site, http://www.flexus.com.
It is widely rumored that the sources for this compiler are available from a BBS. This no longer appears to be the case. Numerous attempts
have completely failed to track down the sources.
There is a COBOL701.ARJ archive that contains a version of COBOL 6.50 with a limited number of compiles. It was an attempt at a full
integrated development environment, including an editor. Unfortunately, no documentation is included.
Also, it may be possible to run the freely available CP/M compiler (see 4.5) under a freely available CP/M emulator.
4.2 for Windows?
For information on the getting the "not latest but free version" of the Fujitsu compiler, see 5.3.2 FREE Fujitsu COBOL Version 3 Starter Set
NOTE: Although not free, a number of vendors provide discounted versions of their products for “academic” use. See the specific
vendor’s information for details on these offerings.
4.3 for UNIX?
There are no well-documented examples of a freely available COBOL compiler for UNIX. COBOL 6.50 might run under a UNIX emulation of
a DOS system, however. (For example, VP/ix, SoftPC or dosemu under Linux.)
The CP/M compiler (see 4.5) should run under a CP/M emulator for UNIX in a similar fashion.
4.4 for the Macintosh?
Not that we know of.
4.5 for Amiga?
According to HarriottC@cardiff.ac.uk (on March 2, 1998),
There is a freely available COBOL compiler/interpreter (Amiga WB2.0+). GUI/CLI, largely ANSI'85 compliant takes the form of Microsoft
COBOL 2.xx ?)
This is available as postware via Aminet Dev/lang nrcobol_1?.lha
4.7 for other environments ?
There is a freely available CP/M COBOL compiler/interpreter (NPS Micro COBOL). This is available via anonymous FTP from
oak.oakland.edu in /pub/cpm/cobol. However, Stefano Priola (s70829@galileo.polito.it) comments :
"I've used the CPM COBOL ... I think that this compiler is much too old to use or for a student to learn COBOL."
5. Commercial COBOL Products (Compilers)
In order to present an un-biased list of commercial COBOL product offerings I've pulled in the product overviews from each company's
marketing information. For detailed product descriptions, you should probably contact the specific vendor.

5.6.2 LegacyJ DDS Plug-in
LegacyJ DDS Plug-in permits the use and display of OS/400 DDS screens on any platform supporting Java. The LegacyJ DDS plug-in is the
natural extension for COBOL and Java functioning with screens defined using IBM’s OS/400 Data Description Specification (DDS).
The DDS screen definitions, familiar to the OS/400 community, remain valuable and can continue to be used to define user interface
interactions. The screens can be leveraged with the use of the DDS Plug-in, and unlike screen scraping, DDS screen definition records are
controlled and displayed on the platform where they are deployed.
PERCobol in conjunction with DDS Plug-in maintains the same behavior as it did when solely resident on the iSeries while enabling the
COBOL application to access data remotely on the iSeries server.

5.10 WANG
Information received on March 11, 2002,
“Wang's COBOL ReSource is alive and well, running in AIX on RS/6000 and HP/UX on HP-9000. Sites running 300-500 users in
shared, indexed files are not unusual and a site or two runs over 1,000 users. All the key components are ports of Wang VS code,
including the very able file system.
Care of the product was outsourced by Wang to SRDI of Australia a few years ago, before Wang was acquired by Getronics. I
represent SRDI in most parts of the world and am the focal point for most new migrations from Wang VS to COBOL ReSource. I do
not have any performance comparisons of ReSource against MF or AC but I have comparisons of ReSource on modest RS/6000 boxes
against a range of Wang VS models and a couple of HP models. Wang's COBOL 85 generates native assembler code, then assembles
it and links it using the native tools, all automatically, on all three platforms that support it -- the Wang VS line and COBOL ReSource
on RS/6000 and HP-9000.”

7. What about COBOL standards?
7.1 What standards exist?
The current COBOL standard is the ISO/ANSI '85 standard. This replaced the ANSI '74 standard.
There are two amendments to the COBOL '85 standard -- intrinsic functions and corrections.
The ANSI (J4) and ISO (WG4) groups are working on created the next Standard. See below for its current status and contents.
7.2 Can I get the standards via FTP?
The current Standards are not available for FREE via FTP.
However, they can be purchased (at least in the US) by going to:
http://webstore.ansi.org/ansidocstore/find.asp?
And entering “COBOL” as the word to find. The “result list” will allow you to purchase downloadable copies of the existing Standards.
Note: See the next section for information on obtaining a copy of the draft of the next COBOL Standard.
The status of the “copyright” versus the “acknowledgement” makes it uncertain whether – once purchased – one may or may not distribute
copies of the existing (or next) COBOL Standard. Contact your own legal advisor for their opinion.
7.3 What is happening with the draft of the next COBOL Standard and what is in it?
NOTE: To see (or download) a copy of the latest draft of the next COBOL Standard, go to the J4 “external web site” and find a link to the
“latest and greatest” version from there. The external J4 web-site is at:
http://www.cobolstandards.com/
This site also provides all the information on the current status of J4’s work and links to various related sites)
First "9x" has become "0x". After the last public review, it turns out that there will need to be at least one more public review before it gets
approved.
1.
Major features/enhancements:
A. OO gets all the press
B. Common exception handling, C-ification (pointers, call prototypes, typedefs, and everything else needed to use C-type APIs),
user-defined functions, file-sharing/record-locking, 31-digit numbers, portable arithmetic, National character handling
(MOCS or DBCS but more so), are all some of the "biggies" that some people are looking for.
C. In the category of "old technology" getting a new face lift and being added to the Standard (as required) see Report Writer
enhancements, VALIDATE feature, and character screen I/O support via ACCEPT/DISPLAY.
2.
Little things (and there are too many for me to remember off the top of my head) include everything from dynamic file assignment (in
the SELECT/ASSIGN statement), assigning multiple values via the VALUE statement in tables, sorting tables, hex literals, GOBACK
verb, apostrophe as quote, bits and Boolean support,
and LOTS more
8. COBOL 6.50
8.1 How do I compile my programs?
It is assumed you have installed cobol650.zip in the directory C:\COBOL650. In install.doc you will find some information on running the
compiler.
1) Add C:\COBOL650 to the PATH
2) Run APPEND on C:\COBOL650 :
APPEND C:\COBOL650
3) The install.doc contained in cobol650.zip refers to a program DPATH.COM to be run instead of APPEND. The DOS program
APPEND seems to work too.
4) Now you can compile your .cob files as explained in install.doc.
When trying to compile sources in a directory other than that where the compiler is installed, the compiler terminates without an error. This
restriction is not documented in install.doc, which is probably a result of using APPEND instead of DPATH.
The compiler accesses drive A:. You should have a disk in this drive.
Peter Mikalajunas adds:
To avoid the need to use drive A:, you should do the following :
subst a: c:\cobol650
When you type A: you will drop into the C:\COBOL650 subdirectory. The compiler will behave normally at this point, not constantly
searching drive A:.
When you are done with a session do the following :
C:
subst a: /D
8.2 How do I link my objects ?
There is no linker with the COBOL 6.50 compiler. To link objects you need to use the linker from MS-DOS v3.3 or earlier.
Ralf Laemmel adds :
You can use newer linkers, especially from newer Microsoft compiler products, too.
And Peter Mikalajunas has found that :
Tlink compiled with obj files without complaint, but the exe's were useless. What did work was Link version 5.31.009 which comes with
Visual Basic for DOS. It compiled all obj files I tried and the EXEs ran perfectly.
Clinton G. Downing also reports :
The linker from IBM DOS v2.1 does now work, at least on the PS/2 70. The MS-DOS v3.3 linker works fine, however.
Steve ??? <steve@mado.demon.co.uk> has reported some success with a linker from the SimTel archives. Look for sl101a.zip.
9. What about OO COBOL?
9.1 ANSI and ISO Work
The draft of the Committee Draft (CD !>!) of the next COBOL Standard which underwent public review in 1997 included significant OO
COBOL support. Based on the comments received J4 (ANSI) and WG4 (ISO) or currently revising it (and deleting some features.
9.2 Micro Focus
Micro Focus has an OO COBOL product. It does not conform exactly to the OO COBOL proposal currently being discussed, however -- the
syntax is a subset of the current proposal with a few variations. Multiple inheritance, conformance and garbage collection are not implemented.
Also, vocabularies are implemented though these are not currently part of the proposed standard. (See Micro Focus' product section.)
9.3 IBM
IBM offers OO COBOL products for MVS, OS/2, Windows, and AIX. (It does not currently offer it for OS/400, VSE, or VM). There
implementation is a subset of s snap-shot of the Standard as it was in 1995. The latest mainframe compiler uses a Java-based OO model.. (See
IBM's product section.)
9.4 Fujitsu
Fujitsu's various COBOL products also support OO COBOL with or without GUI interfaces. (See Fujitsu's product section.)
9.5 Others
I believe that other vendors are at various stages of developing, testing, and distributing OO COBOL products. For specific product
information, you should contact the vendor (such as Fujitsu (Siemens), Hitachi a, Computer Associates, etc)

“A good introduction to COBOL for the beginner. It doesn't give many full programs to see, but it does help understand the way the
language works.”
***
To install the Fujitsu compiler that comes with this book, you will need to enter a serial number that was accidentally left out of the first
printing of the book. (For later editions, this is not a problem).
It will install with this number:
103-2001 1699-03317-70168
The first part of the number should already be in the window, so all you will have to enter is:
99-03317-70168
Another reported problem with the Fujitsu compiler provided with this book is linking of programs. The following information on the problem
and solution was provided by Thane Hubbell on March 20, 1998.
"When Linking you will get a warning message that says:
No Entry Point
The program continues to link however. It will not run. Here are the steps to get it to Link properly, eliminate the error message and
run.
>From the WINCOB window - NOT the WORK FRAME window, just the plain WINCOB window, click
OPTION
Click
ADD
Scroll down to MAIN
Click
ADD
Select the option for "Compile as Main Program"
Click
OK
Now the program will compile and link as a main program and life will be just wonderful.
PS: Thanks to Robert S. Robbins for these instructions, I do not know if he still monitors the group, but he deserves the credit."

10.12 “COBOL Unleashed”
ISBN: 0672312549
By Jon Wessler
1021p, September 1998
COBOL Unleashed presents real-world solutions to the key programming problems facing COBOL programmers today. These solutions will
be presented in a topic-by-topic method that will allow the reader to skip around the book to find the solutions key to them, without having to
read the entire book from start to finish. Key topics include: - Year 2000 Problems and Solutions. - Legacy code migration, maintenance and
reengineering. - Interoperability and compatibility of legacy systems. - Client/Server COBOL. - COBOL Database programming. - Transaction
Processing. - Dynamic File Allocation. - Object-Oriented COBOL and COBOL 9X. - Tools and Vendors Appendix. - Syntax Reference
Appendix.
Per Bob Howell [rahowell@worldnet.att.net]
“One of the few books that contains anything about IDMS. It also covers other database types. A comprehensive COBOL reference.”
NOTE: If you get a copy of the first edition, you should be aware of a problem with the Fujitsu compiler provided with the book. The
following correspondence came in from a person at Casegen,
“May we apologize to everyone who has tried using Casegen COBOL for Windows supplied with the CD on "Cobol Unleashed" and had
problems compiling their programs. You will have received this message:
“Registry error - cannot find compiler registry key...”
This problem is due to an error with the Fujitsu compiler on the CD. For some reason the compiler does not get installed correctly and Casegen
needs this compiler to build Cobol programs generated by Casegen.
It will be necessary to install Fujitsu Version 3 or Version 4 from another source to use Casegen.”
You should be able to contact the publisher of the book, Fujitsu, or www.adtools.com to get an updated (corrected) version of the compiler.

"This book is written around two themes: the design of structured computer programs based on the techniques from Jackson
Structured Programming (JSP); and the methods available for coding these designs in the COBOL language."
According to David Silber [DavidS@hpd.co.uk],
“This is an introductory text on COBOL, though heavily geared to the implementation of JSP with techniques such as Schematic
Logic, Structure Clashes and Program Inversion discussed as well as Program Structures from File Structures. Definitely geared to mainstream
commercial EDP.“

BTW, the editor coming with it isn't very good either. This is not meant to be a complaint, just a hint for future issues. I never expected a fully
unlimited compiler for a book price, just a few less limitations.

“An excellent COBOL book which uses new, modern techniques for program design. There are numerous examples, clearly
illustrating various COBOL instructions, which approach real-world standards, more so than other COBOL books. Clear explanations
for beginners, but has so much information that experienced programmers can use it. Examples are easily understood and use a userfriendly terminology.”

Card catalog description
This complete guide acquaints you with significant differences between major COBOL releases, describes how to get the most out of
the newest features, and boosts your upgrade effort with techniques used by one of the largest Y2K factories in the world - Ernst &
Young's Accelerated Conversion Center. You'll find step-by-step methods for comprehensive planning, converting, compiling, and
testing for each of the three different approaches to upgrading COBOL: manually, using internal staff and resources; using purchased
or leased conversion tools; and outsourcing to an established upgrade factory.
11. Is there a COBOL to C converter ?
Asking this question anywhere appears to generate much general flaming and general language wars and very little useful information.
No such beast is listed in the free compilers FAQ, but an ad has appeared in the US publication "Programmer's Shop Catalog" for COBOL to C
(and PL/I to C) translators. Contact :

and
13.5.12.1 CobolTransformer
Another (semi-related) question concerns COBOL to Java translators. Although intended as a COBOL compiler, if you are interested in this,
you might want to check out:
5.6.1 PERCobol™
A toolset for conversion from COBOL to several other languages is available. A tool first produces structured diagrams (Nassi-Shneiderman)
from existing source files. Structural errors are identified and you can edit to correct them. Another tool takes those same diagrams and
produces source code in one of several languages (COBOL, C, ADA, Basic, Clipper, dBaseIV, Fortran, Modula 2, Natural, PL/1, etc.)
The toolset is called XperCase by Siemens, and is available in the US from:

"Some years ago I was Project Leader on a software project termed COBTOC (COBol TO C translation). The company is by now out
of business, but the rights on this product were purchased by NSI (Network Solutions Inc., Herndon, VA, USA - Emitt McHenry was
Chairman).
COBTOC is actually a translator generator. It can produce a specialized translator for any reasonable COBOL dialect, given a dialect
description very close to the usual syntax notation one can find into any COBOL Reference Manual. "semantics" peculiarities are also
described in this way.
Once a translator has been produced in this way, a source management module allows automated translation of the COBOL source
modules. A run-time library is also automatically produced as a by-product of the translator.
The COBTOC user gets a set of C files, each being the translation of a corresponding COBOL file. You can get K&R C, ANSI C, or
common variants like Turbo C. The overall structure of the COBOL program is preserved upon translation. Identifiers are
straightforward transformations of COBOL names. Paragraph structure and flow control are also preserved, like all name space
properties attached to I/O and file management.
The C files are compiled and linked with the run-time library, which supports data handling, edition, arithmetic, direct I/O, file I/O
and transaction management (e.g. CICS).
Executables are intended to run on any platform supporting POSIX C compiling and standard library linkage.
COBTOC was left by my co-workers and me in an alpha release state, mid 1993.
I don't know the end of the story, but NSI should provide more up-to-date information about it.
There is also a project running to create a COBOL to C converter (possibly COBOL to C++ ?) available under the GNU license. "
Another project that can be viewed as either a COBOL to C converter or as a compiler, is the "CobCy Project"

13. COBOL Tools
This section documents some of the add-on tools that are available for use with COBOL compilers. Further submissions are welcomed, but
please try to keep them as free from marketing "hype" as possible.
Note: This section seems to be entirely devoted to tools that run in or are targeted at the PC and/or Unix world. Mainframe additions are
welcome, but will probably be a while before I can add them.
13.1 Creating GUI's
13.1.1 Acucorp GUI products
AcuBench
AcuBench is an integrated development environment for ACUCOBOL.-GT. Available for the Windows 95 and Windows NT operating
systems, AcuBench combines the internationally acclaimed ACUCOBOL-GT (Graphical Technology) compiler and runtime system with a set
of graphically-based, GT-optimized WYSIWYG screen Painter, and language sensitive source Code Editor.
ACUCOBOL®-GT
ACUCOBOL®-GT enables COBOL programmers to implement and deliver full-featured GUI COBOL applications on any of over 600
platforms, with full object code portability using a single set of COBOL source code. Programmers can create graphical applications including
floating windows, graphical controls (such as entry fields, frames, radio buttons, push buttons, and labels), menu bars, bitmaps, and toolbars
using COBOL extensions that are consistent with traditional COBOL syntax.
13.1.2 Flexus COBOL spII
COBOL spII allows the COBOL programmer to create GUI or character mode screens using ANSI standard COBOL CALL USING
statements. COBOL spII screen definitions and source programs are 100% COBOL compiler independent, 100% operating system
independent and 100% text mode to GUI mode independent.
Automatic screen conversion tools for many proprietary environments are also available from Flexus. These automate the task of converting
screen definitions from proprietary character mode screens to GUI screen definitions.
For more information: see
http://www.flexus.com/
13.1.3 Fujitsu PowerFORM™
(See http://www.adtools.com/products/windows/pform.htm)
PowerFORM is a WYSIWYG graphical form designer and layout tool for creating complex print forms. You can easily replace your traditional
plain text reports with graphical COBOL reports. PowerFORM lets you design reports with graphical elements, color, and variable fonts and
then print them on any laser or inkjet printer. It is closely integrated with Fujitsu COBOL so PowerFORM reports are defined and written using
COBOL file handling syntax. In fact, programming in PowerFORM is almost identical to writing a regular print file.
13.1.4 LegacyJ BlueJ™
NOTE:
I can no longer find information on this product at the LegacyJ site.
BlueJ is a graphical application painter utilizing graphical and non-graphical program elements to create application programs in Java or
PERCobol (COBOL). BlueJ combines the features of a conversion tool and a graphical application painter. Import filters paint text elements as
configurable graphical elements and allow these elements to be enhanced. Graphical palette items can be supplemented with commercial Java
Beans or tailored elements provided by LegacyJ to create new programs.
BlueJ delivers active element programming; enabling programmers to view element interactions while the program is being built. BlueJ will
generate and compile both COBOL (PERCobol) programs and Java programs. Programs developed with BlueJ can contain COBOL Beans
(generated with LegacyJ PERCobol) and Java Beans commercially available from a wide range of sources.
BlueJ enables programmers to add active elements to an application "form", and visualize the "touch and feel" of the application as the program
is being assembled. An interaction wizard is used to connect objects and actions.
BlueJ is a highly configurable graphical application tool. It has the capability to add input and output filters so that non-graphical terminal
applications can be "screen scraped" and used as input to then generate a basic graphical screen. This basic screen can then be enhanced adding
new graphical elements.
Output filters (Application Programming Interface) can be used to attach additional code generators for other programming languages.
For the latest information, the following site previously was used:
http://www.legacyj.com/bluej/index.html
13.1.5 Norcom GUI ScreenIO
GUI ScreenIO, a graphical user interface for COBOL, is Norcom's newest and coolest product. Powerful, rich in features, and remarkably easy
to use. If you want to develop true Windows® applications using COBOL, you want GUI ScreenIO.
For more information, see:
http://www.screenio.com/products.htm
13.1.6 VanGui for RM/COBOL.
VanGui consists of two major components: a design tool and a runtime system. The design tool is a Windows application which provides
COBOL developers with the capability to define windows, populate those windows with standard Windows and VBX controls, adjust the
properties of those controls and attach COBOL event-handling logic to their events.
The VanGui Runtime is a Windows .DLL that manages Windows messages, provides runtime support for the controls, and provides a COBOL
interface to the Windows API.
For more information on VanGui, see
http://www.liant.com/products/rmcobol/vangui/
For another GUI tool from Liant, see 5.3.4 RM/Panels
!3.4 What about Year 2000 Tools?
As far as I can tell, there are no longer any tools specifically marketed for Y2K issues. Many “re-engineering” and analysis tools can (could)
be used for this and similar (e.g., EURO) conversion efforts. Although I don’t know how current it is, if you are interested in such tools, you
might want to check out:
http://www.y2ksavers.com/pages/resource.htm#software
As well as looking at:
What about the Y2K (Millennium) Issue?
13.5 Misc. Tools and Services
13.5.1 Clone Doctor
The Clone Doctor finds and locates exact and near-miss clones (duplicated sections of code and/or data declarations) in large (COBOL)
application suites, and optionally removes them. It typically finds 10-20% by code volume. Removing such clones can potentially save
maintenance costs an amount proportional to the size of the removed code. An additional benefit is that often detection of clones will show an
incorrectly modified clone, thus demonstrating a bug. Since the Clone Doctor is based on the DMS Reengineering toolkit, it can handle
massive application systems in multiple languages.
A demo version for COBOL85 is available from their Web site at:
http://www.semdesigns.com/Products/Clone/index.html
13.5.2 COBOL Explorer
COBOL Explorer is a web-based facility to archive and view (IBM mainframe) COBOL / JCL listings in a hyper-text medium. It is a
maintenance-friendly medium. Both COBOL and JCL are full of cross-referenced items that are tedious to follow. We believe that the time has
come to re-present the information in an intuitive way so we can improve maintenance productivity by an order of magnitude.
COBOL Explorer is an active fully cross-referenced and searchable repository. You can navigate from program to program to JCL and back at
a specific timeline, all without any regimentation, installation or any work at all!
For additional information, the following (now defunct) web-site was available:
http://www.cobolexplorer.com/
13.5.3 DMS Reengineering Toolkit
The DMS Reengineering Toolkit is a suite of tools for automating the analysis and modification of large-scale application suites, in COBOL
and/or other languages. This enables organizations to carry out changes that are not practical or reliable by hand, such as porting, database
rehosting, database and application conversion, documentation extraction, etc.
The toolkit provides facilities for:
Parsing legacy languages (COBOL85, IBM COBOL VS2, C, C++, Fortran, Pascal, SQL, VisualBasic; other languages can be defined).
Software systems with mixed languages, thousands of files and several million lines can be processed in a single session as a unit. Applying
customer-defined transforms written in the syntax of the legacy language (e.g., COBOL) to carry out desired changes. Prettyprinting the
transformed results, optionally reproducing the unchanged portions with the original spacing, formatting and comments.

VAX/VMS and Open VMS.
For more information, see:
http://www.rxcomputer.com
13.5.5 Flexus WinPrint
COBOL WinPrint allows the COBOL programmer to make ANSI standard COBOL CALL USING statements to completely control and
communicate with the Windows Print Manager. Forms may be designed interactively with the Forms Editor to include bitmaps, special fonts,
colors and many other modern features. These reports may be viewed on the screen prior to printing or sent directly to the Print Manager.
13.5.6 J & C Migrations
Translate cryptic RPG and CPG to readable COBOL
CPG, RPGII, and RPG III are proprietary, cryptic, and obsolete, and require specialized Runtime, APIs, licenses, and skills. RPG skills
and tools are not as readily available when urgent work needs to be done. While RPG/400 is not yet obsolete, it is cryptic and proprietary.
In contrast, COBOL is readable, self documenting, has better tools and more trained people for its maintenance. COBOL is the most
common computer language, available on Mainframes, Minis, Unix, and PC environments. COBOL is based on a public Standard, and is the
most portable, and best supported language in all of the above environments.

To find all the RainCode offers related to the COBOL language, see:
http://www.raincode.com/cobollg.html
13.5.9.1 RainCode Engine for COBOL
RainCode actually reads the COBOL source code and builds an annotated parse tree after a fully documented object model. A scripting
language can then be used to walk through the parse tree, taking full advantage of the features provided by the object model.
See:
http://www.raincode.com/cobolengine.html
13.5.9.2 RainCode Roadmap for COBOL
The RainCode Roadmap for COBOL is a RainCode product, which produces documentation out of possibly large amounts of COBOL source
code automatically, in order to ease maintenance, and, more generally, deliver usable knowledge about existing systems.
13.5.9.3 RainCode Checker for COBOL
RainCode is a system that operates on possibly large volumes of COBOL code, and that assesses its compliance versus a number of possible
metrics:



Quality
Industrially accepted, company-wide or project-wide guidelines
Portability
The true added value of RainCode lies in its ability to measure compliance towards user-defined rules that can be expressed conveniently using
an ad hoc scripting-language. This scripting-language operates on high-level structural and semantic concepts. Even the most obscure, the most
exotic guideline can be checked for easily.
See:
http://www.raincode.com/cobolchecker.html
13.5.9.4 RainCode XMLBooster's COBOL Code generator
RainCode XMLBooster's COBOL Code generator:

15. Information required for the FAQ.
Corrections and additions to existing material are always welcome. I'd like to add a section of reviews of different COBOL books. If I am sent
any reviews I will collate them and add these to the FAQ. More information on mainframe COBOL products would be useful.
A section covering COBOL programming could be worthwhile.
Note: I still have a "folder full" of comments sent to the last owner of this FAQ that have yet to be applied. It is my intent to get them verified
and applied as soon as possible.
16. Contributors to the FAQ.
Many people have contributed to this FAQ in each of its iterations. In the past an ongoing list of these people have been included within the
FAQ. At this time, i am stopping this practice, although I ,in no way, want to deprecate all the work and input that these people have provided.
I have continued to identify people whom I am quoting (directly or indirectly) and do still hope that everyone who has input for this document
will continue to provide it.

18. What can/should I post in the COBOL newsgroups?
Both comp.lang.cobol and alt.cobol are UN-moderated newsgroups.
This means that there is no controlling authority regulating the content of the posts in those groups. Anyone is able (but most assuredly not
welcome) to post anything, relevant to COBOL or not. Off-topic posts (and particularly prolonged off-topic threads)are discouraged, but it is
impossible to prevent them. Different readers of these newsgroups have different thresholds for tolerating off-topic comments. The more that
you post, the more likely it is that some readers will simply apply a "killfile" to all of your posts - often after sending you (and possibly the
newsgroup) rather pointed comments on your use/abuse of the newsgroup.
You should, therefore, apply the following guidelines that will help you get the most out of both your viewing and postings at these sites.

Comp.lang.cobol is the preferred site to use - especially for technical issues related to COBOL.

Although threads do stray from the topics, the more targeted your inquiry is - and the more closely it relates to COBOL, the more
likely you are to receive a useful and prompt response. (If you know that you are leaving the current subject, consider changing the
subject line in your post.)

When asking about a specific structure, error message, or situation, it is always best to specify both the compiler that you are using
and the operating system where you are working. (What you may think is a general COBOL question may actually be very specific to
your current environment.)
Note: For those who are interested, the "charter" for the comp.lang.cobol newsgroup can be found at:
ftp//ftp.uu.net/usenet/news.announce.newgroups/comp/comp.lang.cobol
18.1 Can I get help with homework via the newsgroups?
Yes, you can get help with your homework via these newsgroups. HOWEVER, that does mean that you will receive help - you will NOT find
many participants who will be very happy if you ask them to do your homework FOR YOU. Some hints that you should consider when
drafting your post for assistance with homework include:

Make it clear from the beginning that you are asking for homework help. (Most of the newsgroup participants are very good at
sniffing out those who try and pose homework questions as "business need" questions - and they are not very polite in replying to such
questions).

Make certain that you specify what compiler and operating system your homework is targeted at. Solutions may vary significantly
based on this. (You might also want to include what text book you are using.)

The more information that you can give that demonstrates that you really have tried to solve the problem yourself (using your text
book, class material/presentations, lab assistance, etc), the more likely it is that you will get useful and friendly responses. If you let us
know what you have found on your own and why you are still uncertain or confused, you will usually get helpful responses; if it looks
like you are asking us questions without trying to solve it yourself, you are likely to get very pointed replies.
NOTE: if you are looking for a COBOL tutor, (and don't want to see the "Do your own homework" notes that occur in the COBOL
newsgroups), you might want to try,
http://www.tutoraid.org/
18.2 Can I post job openings in the newsgroups and if so what should I include?
These newsgroups are an excellent place for posting job openings. Some participants (those with jobs) often wish that less of the bandwidth
was spent on job postings, but, for those who are looking for positions/contracts, these postings are quite useful. There are, however, some
guidelines that you should follow when posting positions - unless you like getting abusive and non-responsive replies to your postings.
Always, ALWAYS, include rates, a range of rates, or your best information on what rates are available. Phrases like "based on experience" and
"competitive" are bound to receive replies questioning your motives. The assumption made by many newsgroup readers is:

that ALL such posts are "trolling" for resumes or rates and not serious job searches.

Try to give the best summary of job location and desired expertise in the subject line of your posting. This will assist you in attracting
readers that are actually potentially interested in your openings.

The newsgroups are international in nature, but are dominated by Americans. If you are posting a position outside the US, please make
it clear whether foreigners are or are not welcome to apply - and if so what visas and other paperwork is required If you are posting for
a job with specific citizenship requirements, please make that clear from the start.

In general, the more information that you provide in your postings, the better the match will be from those who reply. If, however, you
are "attaching" a job description, please make certain that you make it clear what type of document-reader is required to process it
AND make certain that you have virus scanned the document before you post it.

19. What about USAGE? COMP? Storage for data in xyz format? Etc
19.1 For "alphanumeric" data?
For "alphanumeric" data (or alphanumeric edited data), you should be OK, if you simply take the default of USAGE DISPLAY for your data.
In other words, the definition of COBOL insures (more or less) that such data is pretty portable and that each symbol in the PICTURE clause
takes 1 byte of storage. HOWEVER, the only way to really insure that such data is completely portable is to:

Use the Standard-1 (or Standard-2) Collating Sequence

Use the Standard-1 (or Standard-2) CODE-SET for input/output files

Not rely on the order of keys of indexed files
However, in most environments, you should be fairly safe in using the "native" coding system for alphanumeric items - as long as you have a
method of converting such data from environment to environment (for example - an upload or download system that converts from ASCII to
EBCDIC) if this is now or may ever be an issue for your application. The problems you might encounter with such data include:

Comparisons not working (are alphanumeric numbers "smaller" or "larger" than "letters"?)

What order are indexed files stored in?

Remember that "true" ASCII (Standard-1) only includes 7-bit characters.
(All the "extended" characters or the "top-half" of most common ASCII environments are NOT standard and are not necessarily
portable)
19.2 For "numeric" data?
When it comes to numeric fields the *ONLY* way to insure "portable" numeric fields is to define them as:
USAGE DISPLAY
SIGN IS SEPARATE
Such fields may need to go thru the same type of ASCII/EBCDIC conversions as alphanumeric data, but they will retain their complete
numeric values. HOWEVER, this type of numeric field is highly INefficient in some operating systems and with some (most?) COBOL
compilers. If a field is just used for input/output from external devices (files or screens), then this definition may serve you well - but if you are
doing a lot of arithmetic - or interacting with other operating system "programs", it is possible (probable?) that you will not be able to use this
format in resource/time-sensitive applications.
19.2.1 For "portable numeric" data?
"Standard" more or less numeric data types include USAGE BINARY and USAGE PACKED-DECIMAL. These were introduced in the '85
Standard and provide for portable source code - but NOT NECESSARILY PORTABLE STORAGE. Taking the most simple example,
05 How-Many-Bytes Pic 9(04) Packed-Decimal.
may be stored as either 2 or 3 "bytes" (a concept that isn't in the current Standard - but will be in the next one) of storage - depending on
whether your compiler "requires" a sign-nibble for even unsigned packed-decimal items. The general rule is that all "meaningful" digits of a
packed-decimal item take 1 nibble (half of a byte) and the sign takes another. But when the data definition does NOT include a sign (S), then
some systems still require the storage and some don't; some store an unsigned numeric field with the same sign-nibble as a positive number and
some don't. (Most common examples - Most IBM-compatible PC's treat positive and unsigned numeric fields with a X'3' sign-nibble - while
most IBM compatible mainframes treat positive numeric fields with a X'C' while unsigned have a X'F' sign-nibble).
The standard USAGE BINARY has even more variations. (The Standard says that its exact storage is "hardware dependent".) Therefore, your
system may

allow 1 byte binary fields (or may require half-word as the smallest storage)

may use 1 or 2's complements for negative numbers

may be "big-endian" or "little-endian"
All of these ARE hardware/operating system concepts, so you need to check your specific environment to determine their relevance (especially
if you don't know what the concept means).
19.2.2 For "less portable numeric" data?
USAGE COMP (or COMPUTATIONAL) is a Standard definition (unlike COMP-1, COMP-2, ... COMP-n or COMP-x). HOWEVER, what it
means is totally implementor defined. There is a common MISCONCEPTION that the Standard requires USAGE COMP to be the "most
efficient" USAGE for numeric fields (I have even seen this quoted in some manuals). However, this requirement certainly does NOT exist in
the current ANSI/ISO Standard. Nevertheless, often (but definitely NOT always) this USAGE is the most efficient for numeric fields used in
frequent arithmetic operations.
Some common meanings of USAGE COMP include:

USAGE BINARY (on IBM mainframes)

USAGE PACKED-DECIMAL (on IBM COBOL/400)

USAGE DECIMAL (on ???)

USAGE COMP-5 (or COMP-X) (on some Unix or PC compilers)
Without checking your compiler's documentation, you simply canNOT know which it is. Furthermore, your compiler MAY have a compiler
option or directive that will switch it from meaning one thing to another. (For those that mean BINARY, all the variations listed above apply
here as well.)
19.2.3 For "non-portable numeric" data?
Once you get to the non-Standard USAGE COMP-n, "all bets are off". Because, IBM mainframes USED TO dominate the COBOL world, the
following meanings are quite common (but are certainly far from universal):

COMP-1 - Short Floating Point

COMP-2 - Long Floating Point

COMP-3 - Packed-Decimal

COMP-4 - Binary
Other common USAGEs are:

COMP-5 - "native" binary

COMP-X - "native" binary (allocated by bytes, not digits)

COMP-6 - Packed-Decimal not requiring sign-nibbles.
******
19.3 Well, What can you tell me?
OK, so now you STILL want to know how many bytes some data field takes (or what the values within a numeric field "mean"). Clearly the
best way to get the answer to this (for anything other than USAGE DISPLAY SIGN IS SEPARATE) is to
CHECK YOUR compiler's LANGUAGE REFERENCE or USER MANUALS!!!
However, if you don't have access to the proper documentation, the answers for various implementations have been given (often) in the
comp.lang.cobol newsgroup - and a check of google.COM (see elsewhere in the FAQ for how to get there) should provide you a good answer.
If all else fails, please do ask the newsgroup for help, but make certain you EXPLICITLY say:

What compiler you are using What Operating System you are running on and

Why you couldn't find the answer already in either google.COM or your documentation
Given the answers to these 3 questions, you will probably get a quick and accurate answer - without them you will usually get a "rather
pointed" reply.
P.S. Never, NEVER, use a "REDEFINES" where you change the USAGE of a field - and expect the application to be portable from operating
system to operating system - much less from compiler to compiler!
20. How do I get started with COBOL? Where can I get education? Tutorials? Etc
20.1 Some places to start – for “teaching yourself COBOL”
There are a number of books listed above that are useful for “teaching yourself COBOL.” One of the ones most frequently recommended in
comp.lang.cobol (partially as its author is a frequent contributor) is:
“Sam's Teach Yourself COBOL in 24 Hours”
Many of the other books are also targeted at this “audience”. Many of the others (like this one) include a COBOL compiler (software) with the
book. Check the detailed list of books for the one that best meets your needs.
It should also be noted that a number of the “commercial vendors” of COBOL compilers provide “academic” programs. See for example:

Micro Focus Academic Products

LegacyJ Educational Program
20.2 Online and Trainer-led Courses and Tutorials
20.2.1 The Trainer’s Friend
The “Trainer’s Friend” does application programmer training for installations using IBM mainframe software (primarily MVS, OS/390, and
z/OS systems, but we also do some Visual Age and WebSphere). In addition, we offer courses in Oracle and Java which may be taught for a
variety of platforms. See:
http://www.trainersfriend.com
There is current list the COBOL-related courses at:
http://www.trainersfriend.com/COBOL_Courses/cobolcurr.htm
20.2.2 University of Limerick – Department of CSIS
The University of Limerick, Department of CSIS provides a site that contains COBOL lecture notes, COBOL Programming Exercises with
sample solutions, a large number of example COBOL programs, tutorials on the COBOL Report Writer and a comprehensive set of COBOL
tutorials making a full COBOL course. It supports the COBOL programming modules taught at the University of Limerick
See:
http://www.csis.ul.ie/COBOL/default.htm
20.2.3 Schools Offering IBM Mainframe Courses
The site
http://www.mainframes.com/schools.htm
provides a list (with links where available) to schools offering S/390 related courses and/or degrees. Many, but not all, provide COBOL as part
of their curriculum.
Appendix A - Samples and Examples of COBOL Coding techniques
For a link to several other COBOL related links - including several with "sample" source code (to solve "real world" problems), see:
http://www.infogoal.com/cbd/cbdprj.htm
Appendix A.1 - Date - 4-digit year
The simplest way to get today's date with a 4-digit year (assuming a current ANSI/ISO compiler - with Intrinsic Functions) is:
01
Current-4-Digit-Year-Date.
05 YYYY
Pic 9(04).
05 MM
Pic 9(02).
05 DD
Pic 9(02).
***
Move Function Current-Date (1:8) to Current-4-Digit-Year-Date.
If you then want to convert that "Gregorian" date to a "Julian" date, you can add the following code.
01
01
Current-Num-Greg-Date redefines Current-4-Digit-Year-Date
Pic 9(08).
Current-4-Digit-Year-Julian-Date.
05 YYYY
Pic 9(04).
05 DDD
Pic 9(03).
01 Current-Num-Jul-Date Redefines Current-4-Digit-Year-Julian-Date
Pic 9(07).
***
Compute Current-Num-Jul-Date = Function Day-of-Integer
(Function Integer-of-Date (Current-Num-Greg-Date)).
End-Compute.
FYI, if you have a compiler with extensions to the ACCEPT statement taken from the draft of the next COBOL Standard, you may also be able
to use the following code (instead).
Accept Current-Num-Jul-Date from Day YYYYDDD
Appendix A.2 - Date Comparisons
Assignment:
The "sample assignment" is that you are supposed to verify that an "input date" is no more than 60 days "old". (For any specific programming
requirement or design, you will need to adjust the code accordingly.)
NOTE WELL: Some code is omitted and some code could be combined, re-ordered, or modified for "performance" reasons. This also
assumes that the "input date" has already been validated to be a "good date" and as a date after 1600.

Appendix A.5 - How can you convert a number to words
Is there a way to write a COBOL program that will convert numbers (expressed in digits) to words (as you do in a check - for example)?
Yes, two frequent contributors to comp.lang.cobol have provided sample source code to do this.
For a relatively "simple" version (that only works for English), see
(Thanks to Thane Hubbell, cf. 10.18 "Sam's Teach Yourself COBOL in 24 Hours")
http://www.geocities.com/Eureka/2006/download.htm
and look specifically for (zip file):
http://www.geocities.com/Eureka/2006/cutenum.zip
For a more complex solution (which handles multiple languages and also includes support for converting "dates" as well as numbers), see
(Thanks to Leif Svalgaard and our friends at "ETK")
http://home.comcast.net/~wmklein/FAQ/ETK/ETKPAK.zip
