PERFORM ... VARYING ... AFTER

Certain identifiers in the VARYING phrase of the PERFORM statement are set and incremented differently depending on whether CMPR2 or NOCMPR2 is in effect.

Identifiers are set and increment differently, for example:

PERFORM PARA3 VARYING id-2 FROM id-3 BY id-4
              UNTIL condition-1
        AFTER id-5 FROM id-6 BY id-7
              UNTIL condition-2.
