Help! GO TO and PERFORM THRU!

It has been a while since I posted a summary of "approaches" to the LOOP wit
h
immediate exist issue - with summary comments on the PHILOSOPHICAL issues wi
th
"GO TO and PERFORM THRU".

Comments in no particular order.

1) For some (unknown to me) reason, the use of SECTIONS is more common in Eu
rope
while the use of PARAGRAPHS without SECTIONS is more common in the US.  (Thi
s
may impact the programming style).

2) The '02 Standard introduced "EXIT PERFORM <CYCLE>" syntax which is a good
 way
to exit from within an inline loop.  EXIT PARAGRAPH and EXIT SECTION provide
similar functionality for performed paragraphs and sections.

3) If one is coding in (or maintaining) programs in the "older" pre-85 Stand
ard
(no scope delimiters or inline performs), a (possibly the most  common in th
e
US) way to handle "loops" with immediate "problem" exits was something like.
:

001-MAINLINE.
PERFORM 100-INITIAL-STUFF THRU 100-IS-EXIT
PERFORM 200-LOOP THRU 200-LOOP-EXIT
UNTIL SOME-CONDITION
PERFORM 900-FINAL-STUFF THRU 900-FS-EXIT
