GenVRowKey Example

Define a data map that contains a record with an array defined by a COBOL OCCURS clause, as follows:

01 RECORD.
   03 FIELD1 PIC X(4).
   03 FIELD2 PIC X(4) OCCURS 3 TIMES.

The data map includes two source rows that contain the following data:

AAAA111122221111
BBBB555566667777

In this example, two rows contain the following identical data:

AAAA 1111

The GetVRowKey() function generates the following unique table rows:

AAAA 1111 1
AAAA 2222 2
AAAA 1111 3
BBBB 5555 1
BBBB 6666 2
BBBB 7777 3
