To display the contents of this section, you must
select a Data Element call in the left area of the tab. In this section, you
must specify where this Data Element will be located in the generated program,
its format and its corresponding data-name. This section also gives you access
to the Data Element editor tabs.
- Data Element
- The called Data Element is displayed here. You can change it by clicking
the Change... button. The values already entered in
the call Definition are kept and automatically apply to the new Data Element.
- COBOL position
- This field enables you to indicate the placement and the sequence in which
the lines entered in this tab will be generated. These characters form the
first two characters of a sequencing number, with the value in the line number
as the last three digits.
Value |
Meaning |
For a batch program |
AA to ZZ and 0A to 0Z |
These values cause the lines entered in this tab to
be generated at the beginning of the WORKING STORAGE Section.
Relatively to the Data Structures called in the -CD Lines tab,
these lines will be generated as follows: - Before the description of Data Structures whose organization is W:
file description in Working and whose code in program matches
this prefix or is greater than it,
- Before the description of Data Structures whose organization is L:
Working with placement, and whose COBOL position matches
this prefix or is greater than it.
|
00 to 09, 1A to 19... 9A to 99 |
The lines entered in this tab will be generated in the WORKING
STORAGE Section, after all the Data Structures whose COBOL
position is lower than this prefix |
For a transactional
program |
AA to 0Z |
The description is generated in the WORKING
STORAGE Section. |
00 to 99 |
The description is generated in the LINKAGE Section. |
AA and 00 |
These values are used by the system for data generated
automatically. |
99 |
With a Line number = 999,
this value is used by the system for the PROCEDURE DIVISION statement.
Therefore, you may use it to create a line with a sequencing number 99999,
which will replace the PROCEDURE DIVISION line which is automatically
generated. |
$n |
This represents a parameterized value in a Macro-Structure |
- Line number
- This line number, constituted of three digits, will be concatenated with
the two characters of the COBOL position. The line
number can be:
- 0 to 999: As a recommendation,
you should number the lines, starting with 10, by intervals of 10, to facilitate
any future insertion
- $n0 to $n9: In a Macro-Structure,
only the first two characters of the Line number can be parameterized.
- Line type
- Here you must select which format is going to be used for the Data Element
call:
- ’E’: Input format,
- ’I’: Internal format,
- ’S’: Output format.
- Text before
- This field is divided into two sub-fields:
- The 'Level or Section', constituted of the first 17 positions of the field,
In this sub-field, you must enter the COBOL level number (01, 05...)
or the Section name (LINKAGE SECTION,...) in which
this line will be generated.
- The 'Work area declaration', which starts from position 18, to the end
of the field. You must declare the beginning of the data-name, which will
be concatenated with the Data Element code to constitute the actual data-name.
So
you must enter
w-ddss- (without omitting the dashes),
where:
- w = Working-storage prefix (alpha or numeric),
- dd = Data Structure code, including the work area,
- ss = Segment code,
Once concatenated with the Data Element code, the data name will be:
w-ddss-eeeeee (with
eeeeee as the Data Element code).
Note: When a Data Element existing in the
Repository is called in a work and link area, you must enter the beginning
of the data-name in this field. Otherwise, the generated code will be formatted
this way:
03 DDSS-DELCO PICTURE X.
- Text after
- In this field, you must enter the characters which will be inserted in
the generated code, after the data-name. Most often, you just enter a period
('.') but you can also enter other values (ex: 'VALUE SPACE').
- Occurs
- You must indicate a number in this field when the data-name (entered in
the Comment field if you are viewing a comment call,
or in the Text before field if you are viewing a Data
Element call) is occursed. You enter here the maximum number of occurrences
for the table. This is a pure numeric field, on 5 characters maximum.
An
entry in this field causes the generation of the following three indices (
ddss =
Segment code):
- IddssM initialized to the value entered.
- IddssL initialized to zero. This index may be used to
load the table. It keeps track of the actual table size
- IddssR initialized to zero. This index may be used for
table searches.
In a Macro, it can be parameterized by assigning it a $n value
If you click the buttons in the bottom part of the section, you open
the corresponding Data Element tabs:
