<syntaxhighlight lang="cobol">
* Pointing out some interesting things:
* - BY 0 subclause of VARYING (illegal in some COBOL dialects)
* - PERFORM THROUGH with internal/external GO TOs
* - using non-reserved keywords (END, DATA)
* - ALTER (works the same way in COBOL)
* - fall-through from MANY-BOTTLES
* - the last NEXT SENTENCE does nothing (plays the role of EXIT)
