JCL PROBLEM 2
OBJECTIVE: To familiarize the student with creating a
library, storing a member in the library and printing a
member of the library.
Note: The IEBUPDTE utility program is not covered in the
current OS/390 and z/OS JCL textbook. It was used to
maintain libraries (partitioned data sets or PDSs) via
batch jobs. This function is now mostly performed via ISPF.
The IEBGENER program is covered in detail in Chapter 18.
Code a two step job, the first step will add a member to a
temporary partitioned data set (a library). The next step
will print that member.
1.
In the first step:
a. Execute the program IEBUPDTE
b. Pass the program a PARM parameter of NEW
c. Allocate a SYSPRINT file
d.Allocate a SYSUT2 file to create a temporary PDS.
Use three tracks of primary storage and two
directory blocks. Do not catalogue the data set
but pass it to the next step. Use SYSDA as the
unit device. Record length is 80.
e. Allocate a SYSIN instream file using the
following
cards
./ADD NAME=JCLxxx,LIST=ALL
(Here type in the records on p. 64 in the
textbook.
Use the following format:
1-11
Social Security Number
12-20
First Name

detailed DSCB information. The file resides on the SYSDA volume TSO001.
6. Code an IEBCOMPR job to compare two cataloged data sets named X401.JOURNAL and
X401.JOURNAL.OLD.
7. Code an IEBDG job to create a sequential data set named X401.MASTER.TEST with 150byte records on SYSDA volume TSO001. The records should be created with the following
two fields:
Field name
Positions
Format
Test data type
CUSTNO
1-5
Zoned decimal
Sequence numbers starting with 00001 and
incremented by 1 for each record
DATA
6-150
Alphanumeric
Rippled
Generate 5000 records. Allocate space by records to ensure that the correct amount of space
is allocated to the data set.

How to use the sort/merge utility
Exercises
1. Code a standalone sort job that sorts the cataloged file X401.JOURNAL into ascending
sequence using the first 18 characters of each record as the sort key. The output file should be
named X401.JOURNAL.SORT, and it should be assigned 15 cylinders of primary space and
5 cylinders of secondary space on SYSDA volume TSO001. Allocate 30 cylinders of primary
space and 10 cylinders of secondary space on a non-specific SYSDA volume for the sort
work files.
2. Code the JCL necessary to invoke a COBOL program named X401RPT that requires an
internal sort. The program requires the following two DD statements:
X401JRNL: A cataloged input file named X401.JOURNAL
X401RPT: Report output assigned to SYSOUT=A
The sort modules are located in SYS1.SORTLIB. Allocate 30 cylinders of primary space and
10 cylinders of secondary space on a non-specific SYSDA volume for the sort work file.

JCL PROBLEM 4
OBJECTIVE: To familiarize the student with the SORT utility
and the use of in-stream procedures.
1.Code a two step in-stream procedure.
The first step will execute the SORT utility.
The second step will execute IEBGENER to print out the
sorted data set.
2.Use step 1 from problem 2 to create a temporary PDS and
add a member, JCLxxx, to it.
3.Execute the in-stream procedure to sort the member JCLxxx
of the temporary PDS into a temporary output file.
The records are to be sorted into ascending order by
employee number. The second step of the procedure
will use IEBGENER to print out the sorted file.
4.Execute the in-stream procedure again to sort the member
by last name (major key field) and first name (minor
key field) and then print it again.

How to use TSO, CLIST, and REXX
Exercises
1. Code a TSO command that will copy data set MM01.PROD.DATA to MM01.TEST.DATA.
2. Create a CLIST that runs an order processing program called ORDPRC1. The program will
read in two input files and produce one report. The first input file is ORDER.DATA with a
ddname of ORDERS. The second input file is INV.DATA with a ddname of INVTRY. The
ddname for the report is ORDRPT and it produces a SYSOUT data set. The CLIST should
also release any data sets once the program ends.
3. Create a REXX procedure that executes the same program described in question 2.

How to use UNIX System Services
Exercises
1. Code a TSO command that copies a PDS member called MM01.PROD.DATA(ORDERS) to
an HFS file called /usr/data/orders.data. The data is text based and should be converted from
EBCDIC to ASCII.
2. Code an OS/390 UNIX shell command that will move a file named Customer.data from
directory /usr/data to directory /usr/backup.
3. Use the IKJEFT01 utility program to copy an HFS file to another HFS file. The input file is
called /usr/data/Daily.Trans with a ddname of TRANSIN, and the output file is called
/usr/data/Daily.Trans.copy with a ddname of TRANSOUT. The file attributes for the new file
should allow the owner to read, write, and execute the file and any users within the same
group should have the ability to read the file.
4. Code a job that uses the BPXBATCH utility to perform the same move command performed
in question 2. You can name the job output and error files anything you’d like.
