For a display file, a continuation line is generated for
the INFDS and for the INFSR option.
The data structure name for the INFDS option for the
display file, is always ##DSDF, the subroutine name for
the INFSR option is always *PSSR.
For each subfile used in the display file, an additional
continuation line is generated with the SFILE option. It
contains the name of the format to be processed as a
subfile (SnnSFL) and the name of the RRN field
(##RNnn).
For each continuation line, 'nn' is replaced by the format
number.

The details entered on this screen are used to build the
F-specifications.
The file name is the file name entered on the 'Files used
in the program' screen. If an internal name has been
specified, this name will be placed in the F-specification
by IDDOS. An external override must be specified
before a call to this program can be issued. This
override must also be specified at program compilation
time.
The file type for the F-specification is taken from the
'File-type' field on the detail screen.
The file designation is always 'F' (full procedural file).
The record address type is taken from the 'Keyed File'
field on the detail screen. This entry must be 'K' or
blank.
The device type for the F-specification is always
'DISK'.

If an 'A' was entered in the 'Add File' field on the detail
screen, an 'A' is generated in position 66 of the
F-specification, to indicate the program is allowed to
add records to this data base file.
If the 'User Controlled' field is 'Y', the value 'UC' is
generated in position 71-72 of the F-specification.
If commitment control is wanted, the continuation line
for commitment control will be generated.
For each file, a continuation line is generated for the
INFDS and for the INFSR option. The data structure
name for the INFDS option for the display file is always
##DSff, the subroutine name for the INFSR option is
always *PSSR.
For each file, 'ff' is replaced by the file number of the
file in the program.
For each file, additional continuation lines can be
generated for the IGNORE option.
The records to be ignored in the program can be entered
through the 'Files & Formats' function.

Initial indicator Table.
E
##I
50
1
This array is used to refresh the first 50 indicators after
displaying a format.
Initially, the generator will provide the '0' value for each
element of the array.
The programmer can use indicators 01-50 to display
errors on the screen. After displaying the format, the
##I array will be used to overwrite the program
indicators 01-50.
The programmer can use indicators 51-60 to work with
field conditioning,... After displaying the format, these
indicators remain unchanged. If necessary, the
programmer must change them in the user code.
!!! If more than 50 indicators are necessary to display
all the errors, indicators 51-60 can also be used.
In that case, the program must provide for initialization
of the used indicators in the range 51-60.
If more than 10 indicators are necessary for field
conditioning, indicators 01-50 can also be used. In that
case, the programmer must assign assign a value '1' to
the corresponding element in array ##I to keep the
indicator on.

IDDOS uses the data area IDPARM as a means of
communication from one program to another.
When a program is started, the contents of the data area
IDPARM is retrieved and placed in the data structure
##PARM. The data area IDPARM is locked by the
program.
Before a program is ended, the contents of the data
structure ##PARM is written to the data area IDPARM
and the data area IDPARM is unlocked. Therefore, if
information in ##PARM was changed by the program,
the new information becomes available to the new
program.
Consequently, before a call to another program can be
issued by the current program, the data area IDPARM
must be updated and unlocked.
The following information is available in the data
structure ##PARM :

If so, IDDOS generates a key list for the file.
The name of this key list is ##KLff, where 'ff' is the
number of the file in the program.
The key fields are composed of the move part for the
field (See Chapter 'Defining and Designing Data Base
Files' in 'IDDOS: General User's and Reference Guide')
concatenated with the file number.
Of course, the order of the fields in this key list is the
same as the order of the keys in the external file

Each IDDOS program uses a set of parameter lists to
communicate with programs in the execution
environment.
For test purposes, this execution environment can also
be simulated in the development environment through
option 40 on the IDDOS programmer menu.
THE HELP CIRCUIT (if no UIM is used).
The parameters used by the Execution Environment
program IP250RGB (HELP) are :
-
##PGNM : the program name
-
##FLNM : the name of the display file
-
##FRMT : the format name
-
##LNNR : the line number
-
##PSNR : the column number
-
##ERNR : the last used error number
-
##CSFL : the field name
Pressing HELP will show the HELP function for the
field found in the positions ##LNNR/##PSNR.
If HELP is pressed on line 24/27, the second level texts
(Reason/Action) for the error message are displayed.
CHECKING VALUES AND RANGES.
The parameters used by the Execution Environment
program IP020RGB (Value/Range check) are :
- ##DDCD : the attribute field name
- ##CVAL : the value found on the display for the field
- ##OMSC : the description of the value is returned in
this field, if a correct value was found
- ##DBVL : reserved for future use
- ##SWVR : the control switch
'N' : incorrect value
'Y' : correct value
Manual IDDOS 13
RPG02
Interactive Program: Detail Description
29
A value or range test can be performed. If a value was
tested, and a correct value was entered in the program
IP020RGB, IDDOS returns the description for this
value (language-dependent) in the ##OMSC field.
This description is then available to be displayed on the
screen.
DATE VALIDITY CHECK.
The parameters used by the Execution Environment
program IP030RGB (Date Validity check) are :
- ##DATI :
the date to be tested
- ##FMTI :
the format of the date to be tested. (the
date format on the screen).
- ##FMTO : the format for this date in the data base
- ##DATO : the date in output format.
If the value '999999' is returned in this
parameter, the date was invalid.
The program IP030RGB can be used to
- perform a validity check on a date
- reformat the date
RETRIEVE THE ERROR MESSAGE TO BE
DISPLAYED.
The parameters used by the Execution Environment
program IP010RGB (Get Error Message) are :
- ##PGNM
: the program name
- ##ERNR
: the error number
- ##MESS
: the error message text
The program IP010RGB returns the error message
description in the ##MESS field (language-dependent).
When using error subfiles in your program, another
parameter list and program are necessary (##PLES).
Manual IDDOS 13
- ##F
: the error number to be displayed
- ##TLCU
: the language code
- ##PGNM
: the name of the program messagequeue
to be used for sending the error.

ERROR HANDLING.
The parameters used by the Execution Environment
program IP099CLI (Error Handling) are :
- ##DSDF : the File Information Data Structure
- ##PGDS : the Program Status Data Structure
- ##RETN : the return value
The program IP099CLI is the route to the error handling
circuit. An abnormal end of the calling program will be
evoked because IP099CLI returns the '*CANCL' value
in the ##RETN field. Only in the case of record lock,
can the user return to the calling program without
cancelling. In that case, blanks are returned in the
##RETN field.
DATE CONVERSION.
The parameters used by the date conversion program
IP031RGB (Century support date conversion) are :
- ##DTIC : the input date
- ##DTOC : the output date
- ##FMIC : the input date format
- ##FMOC : the output date format
- ##DTSV : system value QDATFMT
The program IP031RGB performs a date check, the
century is added when necessary using the AS/400
CVTDAT command. It works for dates between 1950
and 2049. If the output ##DTOC is equal to 999999, the
date is incorrect.

RETRIEVE A VALUE BY PROMPT FUNCTION.
This function can be automaticaly generated. This can
be evoked by entering '*PROMPT' in the text field
when entering command key usage. The parameters
used by the Execution Environment program IP039RGI
(Prompt function) are :
- ##PGNM : the program name
- ##DSPF : the name of the display file
- ##CSRC : the format name
- ##CSFL : the field name
- ##CVAL : the value found on the display for the field
- ##OMSC : the description of the value is returned in
this field, if a correct value was found
- ##DBVL : reserved for future use
- ##FLDN : name of the field for which the prompt
function will be processed or just was
processed
If a value was selected, IDDOS returns that value
(language- dependent) in the ##CVAL field. IDDOS
also returns the description for this value (language
dependent) in the ##OMSC field. This description is
then available to be displayed on the screen.
If no value was selected, IDDOS moves *NONE to
##FLDN. If the cursor wasn't on a field with values
IDDOS moves blanks to ##FLDN.

IDDOS has been designed to handle multiple selections,
without leaving the program.
Imagine a selection program calling a detail program to
manipulate the data. After each successful
manipulation, the called program has to return to the
calling program. If another selection is made,
this program calls the subprogram again. This could
continue until no further selection is made.
As each call to the subprogram is costing extra machine
resources, it is obvious that a more efficient solution is
required.
With IDDOS for instance, we could collect several
selections in a table. This table can be passed to the
called program (Entry Parameter List, IDPARM,...).
In the called program, within the DRV routine, this
table can be processed, feeding the case routine driver
with selections, without leaving the program.
In the END routine, an instruction is included to blank
out the ##EXIT field as long as further selections are
found.

A format is processed according to the following citeria
:
--> The ##NPNT contains the pointer number to start
the conversation for the format concerned. The
value in ##NPNT is placed in the ##RPNT field.
--> The ##RPNT field will be used to drive the format
handling. It will execute an automatic routing,
increasing the value found in the ##RPNT field,
until the value 99 is reached.
If there is no intervention in the user process
points, or with command key entries, the do-while
driver stops the handling of this format, and gives
control back to the program main driver.
The following process points are available for a fixed
format :
- pointer 01 : The initial processing for the format,
including the user process point Vnn.
- pointer 10 : This pointer will perform the same actions
as intended for pointer 30.
- pointer 20 : This pointer will perform the same actions

Within pointer 40 processing :
− ##RPNT will be set to value 50
− ##PREV will be evaluated. This contains the
number of the previously displayed format.
If this previously displayed format differs from the
one to be sent, all data and constants will be sent.
If the same format is to be redisplayed, the
PUTOVR condition will be activated (indicators
81,82,91 on).
In that case, only output and both fields will be
redisplayed by IDDOS. If there is no need to
redisplay the output fields, the programmer must
assign a value '0' to the ##NEW field, and indicator
81 will then be set to off.
− ##OVRL will be evaluated.
This is the switch to decide whether or not to
activate the overlay condition. This field is
controlled by the generator.
− ##INSL will be evaluated.
This is the field containing the number of the
command key line to be displayed. If this field
contains a value less than 1, or larger than the
highest possible number of command key line for
this format, it will be reset to the value 1.
IDDOS will then send the appropriate message line.
− When using error subfile, the control format of the
error subfile is written.
− The display format will be displayed and the
##PREV field will be updated

Within pointer 50 processing :
− ##RPNT will be set to value 60
− Help processing is available :
If indicator 99 is in effect (Help key was pressed),
the help circuit is activated through the call of the
program IP250RGB.
Afterwards, the format will be redisplayed. If you
use UIM help, the help function is handled by
OS/400, the display file and the panel group object.
− Command key 24 processing is available :
If command key 24 was pressed, the scrolling of the
command key panel can be performed. IDDOS will
display the next command key line. If there are no
further command key lines, the first command key
line will be displayed, and scrolling can be restarted.
− Command key to process *PROMPT function is
available :
If the command key was pressed and the cursor was
placed on a field that was not linked to a value table,
IDDOS will retrieve the error message with number
966 to be displayed.
If the command key was pressed and the cursor was
placed on a field that was linked to a value table,
IDDOS will call IP039RGI to select a value.
− The ##I table will overwrite the first 50 indicators in
the program.
− The routine $Cnn will be executed. This routine
comprises the user code in the process point Cnn,
followed by the generated command key processing.

Within pointer 50 processing :
− ##RPNT will be set to value 60
− Help processing is available :
If indicator 99 is in effect (Help key was pressed),
the help circuit is activated through the call of the
program IP250RGB.
Afterwards, the format will be redisplayed.
− If you use UIM help, the help function is handled by
OS/400, the display file and the panel group object.
− Command key 24 processing is available :
If command key 24 is pressed, the scrolling of the
command key panel can be performed. IDDOS will
display the next command key line. If there are no
further command key lines, the first command key
line will be displayed, and scrolling can be restarted.
− Rollup processing is available :
− ##RHnn will be moved to ##RNnn
− ##RPNT will be set to value 20
− the based-on file will be repositioned
− the ##I table will overwrite the first 50 indicators in
the program.
− The program error messagequeue is cleared when
using error subfile.
− The routine $Cnn will be executed. This routine
comprises the user code in the process point Cnn,
followed by the generated command key processing.

The Initialization routine performs the following
functions :
− Definition of the corresponding work fields for each
file (*LIKE DEFN) that are not already defined in
the display file of the program.
− Definition of the key list fields for each file (*LIKE
DEFN).
− Definition of the fields (*LIKE DEFN), which are
used to save the keys of the last record loaded into
each subfile.
− Definition of all the fields not already defined in the
program, which are used in IDDOS parameter lists.
− Definition of fields used in the generator. A first set
of fields is available in each program. A second set
of fields is only available for programs that contain
at least 1 subfile.
− Definition of fields necessary to process a format.
For a subfile format, more fields are needed than for
a fixed format. If a format will be presented in
window some additional fields are generated.
− User written initialization code in the INI process
point. It is highly advisable to define each user field
in the program in a data structure in the INP process
point, or in the INI process point. If this advice is
followed, only 2 process points need changing if
field attributes need to be changed.

It is generated for each file in the program, which has an
update or output access defined, except for files only
used in a filecheck.
If date fields were used, date conversion through routine
$U99 could be necessary.
If date fields with century support are included, a call
towards IP032RGB for date conversion is necessary.

This routine is used to convert a date from one format to
another. It is executed from IDDOS routines when
appropriate, and can also be executed from within the
user code. It only works for dates without century
support.
This routine performs the following functions :
− if the date format is 'S', the correct date format is
obtained from the ##DTSV field within the data
area ##PARM.
− the correct date conversion will be performed
− the field ##DATO will contain the converted date.
!!! no date checking is performed in the routine $U99
If you want to convert dates with century support use
program IP032RGB.

The ##TF99 field.
IDDOS has a special way of dealing with multiple
selections in a subfile.
Before the READC cycle is started, the current format
number is stored in the ##TF99 field.
The program can then give control to another format.
When this format has been completely handled, pointer
90 will be processed.
If a transfer control was made by IDDOS, ##TF99
contains the number of the subfile format that control
was transferred from.
Control will be returned to that format, pointer 61, to
retrieve the next record in the subfile.
This can be observed in detail in the example program
in this chapter.
!!! If 'exit' is taken from a format, to which control was
transferred from a subfile (e.g. CF12 on screen 2 in our
example program), this ##TF99 field must be initialized
again to avoid a transfer of control to the subfile, the
first time that pointer 90 is executed again.

Calling another program.
IDDOS uses a data area IDPARM to communicate
between your programs, or to communicate with
programs in the Execution Environment.
Each program, generated by IDDOS, retrieves this data
area when the program starts.
The data area will be locked.
When the program ends, this data area is updated by the
program and unlocked.
If a program must be called, this data area must be
unlocked with the OUT statement.
If control is returned to the calling program, the new
contents of the data area IDPARM must be retrieved
through the IN statement.
As locking and unlocking the data area IDPARM is a
required action, this data area can be used to exchange
information between programs. To achieve this, 256
bytes of information are available in the ##UPRM field.

Program routines.
The names of subroutines in IDDOS interactive
programs are built using the following conventions :
− position 1 = $
− position 2 = A-Z
− position 3-4 = 0-9
− position 5-6 = ZZ (for ENDSR; the first 4 positions
have to be the first 4 positions of the BEGSR name)
Each routine has a different function. The routines
found in interactive programs are :
$Ann Routine, including extra detail instructions to be
executed when a record, which has been
retrieved from the based-on file, must be written
to the subfile.
--> each subfile format
$Bff Routine, used to blank the non-key program fields
for the file with number ff.
--> each data base file, used in the program and
not only used for a filecheck.
$Cnn Post-display command key processing.
--> each format in the program
$Dnn Display navigation routine.
--> each format in the program
$Fff Routine, used to transfer file field contents to the
corresponding program fields.
--> each data base file, if used for input in the
program and not only used for a filecheck.
$I99 General initialization routine (at program start)
--> program level routine
$Inn Routine containing extra detail instructions for
blank subfile records.
--> each subfile format
$Kff Routine, used to transfer program fields to the
corresponding key list fields.

Program fields.
The interactive generator uses a set of predefined
program fields. When adding your own program fields,
you must make sure you avoid conflicts.
Program fields, derived from file fields, are built
according to the following rules :
− For each file in the program, a set of fields is used,
derived from the file fields.
To build these fields, the move-part of the field
name is concatenated with '#f', where 'f' stands for
the number of the file in the program (1-9,A-Z).
− For each keyed file in the program, a KLIST is
defined by the generator. To build the fields in this
keylist, the move-part of the field name is
concatenated with 'ff', where 'ff' stands for the
number of the file in the program (01-35).
Furthermore, a set of program fields is used to execute
particular functions. These program fields start with the
characters '##'.
!!! Because future extensions to the generator will add
program fields to this list, no user-defined
program-fields should have '##' as starting characters.
The functions of these program fields are described
below :
− ##ADnn A(1)
Add-status for format nn. This is used to make 'add'
the default data base access when data base accesses
are generated.
'0' : the add-status is OFF
'1' : the add-status is ON

This field is used to decide if the OVRDTA
keyword for output fields must be active (indicator
81 on).
'N' : OVRDTA not in effect. Output fields on the
screen remain unchanged.
'Y' : OVRDTA in effect. Changes in output fields on
the screen will be displayed.
Initially, this value will be set to 'Y'.
In that case, output fields will be redisplayed.
If this is not wanted, the programmer must assign,
in the user process code, a value 'N' to this field.
The next EXFMT will not redisplay output fields.
This EXFMT however, will reset the value to 'Y'.

decides if the ##OVRL status must be made
effective. ##OVRL is set to 'Y' if the current format
is specified as the format number to be kept in
overlay when the format, specified in the ##NSBR
field is sent.
