There are two ways to have internal loops:

PERFORM VARYING.....
PERFORM VARYING....
IF I-AM-FINISHED
EXIT PERFORM
END-IF
END-PERFORM
END-PERFORM

I am not sure, but I think the EXIT PERFORM will have the ability to
pick which level is being exited from. At any rate, I can't do this
now.


Let's say I want to go the GOTO route as you say. I can't use the
existing code, but would need to rewrite the logic.
IF FOUND-SUBCODE
PERFORM SUBCODE-ROUTINE
PERFORM WRITE-RESULTS
END-IF
...
SUBCODE-ROUTINE.
...
IF FINISHED-SUBCODE
PERFORM CHECK-INVENTORY
PERFORM ADD-TO-BIN
END-IF.
....
CHECK-INVENTORY.
...
IF NEED-TO-EXIT
GO TO ??????
END-IF.
....

Let's say I want to go to PERFORM WRITE-RESULTS at this case. I
need to set up switches or rewrite the logic (which is frowned at with
working code).
