Rational Programming Patterns

Set of Redefines

To display this section, you must select a set a Redefines call line in the list of the elements called in the -CE Lines tab of the current Segment. The Data Element containing this option redefines the Data Element of the same COBOL level which precedes it in the -CE lines of the Segment.

To create a set of redefines in the -CE lines of the Segment, you must check the Redefines option which is available in the different sections of the elements called in the Segment (Data Element call, Definition of a non defined Data Element, Segment call , Filler call, and Group call).

A Set of Redefines line is created in the -CE lines. It contains the redefined Data Element and the preceding one of the same level in the tree structure. You must then define the Occurs option in the Set of Redefines section that shows up when you click the Set of Redefines line. Redefines are possible for Segment calls, groups, and fillers. To create sets of Redefines for these called elements, the procedure is the same as for the Data Elements.
Occurs
Enter a number of occurrences in this field to generate an OCCURS COBOL clause. The COBOL restrictions on the OCCURS clause also apply here. You can indicate a number of occurrences on an elementary or a group Data Element or a filler. The number is limited to 99; it is pure numeric field.
