Rational Developer for System z, Version 7.6

Comment

To display the contents of this section, you must select a comment call in the tree. In this section, you enter a comment and indicate where it will be inserted in the generated program.

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 automatically-generated data.
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.
Comment
This is the actual comment which will be inserted in the generated code.
When used in combination with the Occurs field, you must declare the work areas here by entering their data-names in the following format; w-ddss-eeeeee, where:
  • w = Working-storage prefix (alpha or numeric),
  • dd = Data Structure which includes the work area,
  • ss = Segment,
  • eeeeee = Data Element.
Tthe value entered in this field must be left-justified. The prefix w- may be omitted, but two spaces must then be entered to replace it.
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. This is a 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, you can parameterize it by assigning it a $n value
