Jump to: navigation, search

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. In this case, invoking $FIELDGROUPOCCURRENCE for each iteration of the loop will be prohibitively expensive, and you can save significant processing resources if you label the FEO loop and substitute a simple OCCURRENCE IN label statement for the $FIELDGROUPOCCURRENCE statement, as shown in the following fragment:

    Begin ... example1: feo fieldgroup Foo  %id = Foo.ID  %code = Foo.CODE  %text = Foo.TEXT  %occurrence = occurrence in example1 /? was $fieldGroupOccurrence ?/ end for ... End
