This function returns the current occurrence number of the field group. If the current field group has been deleted, $FIELDGROUPOCCURRENCE returns 0.

$FIELDGROUPOCCURRENCE is available as of Model 204 version 7.5.

Syntax

%num = $FIELDGROUPOCCURRENCE

Example

FOR EACH OCCURRENCE OF FIELDGROUP REDSOX PRINT $FIELDGROUPOCCURRENCE CALL CHANGINGPROC PRINT $FIELDGROUPOCCURRENCE END FOR

This example might print a different value before and after calling the CHANGINGPROC procedure, if that procedure inserted or deleted the field group occurrence before the current one.

Usage notes

  • In a large record, $FIELDGROUPOCCURRENCE is expensive. It intentionally scans from the start of the record, in case there were additions or deletions of the fieldgroup.

    For example, say that a record being processed in an FEO FIELDGROUP loop has thousands of occurrences of a fieldgroup named CORE. In this case, invoking $FIELDGROUPOCCURRENCE for each iteration of the loop will be prohibitively expensive, and you can save significant processing resources if you substitute a simple OCCURRENCE IN CORE statement for the $FIELDGROUPOCCURRENCE statement.
