Lemme see if I've got this right -- never mind so-called 'facts'?

Come on, Doc. You, of all people, know that would never pass muster at
a mainframe code review. They'd make you rewrite it:

PERFORM 60000-CODE-LIKE-HELL
      THRU 60000-CODE-LIKE-HELL-EXIT
      UNTIL PGM-STATUS = lt-00.
PERFORM 20000-NEXT-ASSIGNMENT
       THRU 20000-NEXT-ASSIGNMENT-EXIT.
