RE: Sequence error in MR

[G Armour <garmour400m@xxxxxxxxx>]

'old hat' was not my original term.

The primary reason why I recommend avoiding it is that there is always an
coding alternative that is easier to understand and, most likely, is
better performing.  Simply put, MR exists because the original RPG
required short SHORT "code".

AFAIK, nobody's even teaching MR anymore.  Cozzi, in his Modern RPG-IV,
(2nd ed.), gives a passing reference to matching records ("it exists") but
doesn't explain it.  The several times in my 20-year career that I've had
to maintain/fix an MR app, I've had to go back to the manuals.  As usual,
code examples are not IBM's strong suit.

Tell you what.  Get Cozzi to devote a chapter to MR, and I'll jump on the
bandwagon.

Do you still code indicators in new applications?
