Hmmmmm......

Going to another ILE RPG test program, *START doesn't work for
CHAIN, but it works just fine for SETLL.

SETLL with *START gets me to a "good" record.
SETLL with 1 gets me to an "excluded" record.
SETLL with 0 gets me no record at all.
SETGT with 0 gets me to an "excluded" record.

Interesting, since I'm just about certain that MI is calling
the same thing an RPG SETLL calls, rather than what an
RPG CHAIN calls.


Become 100% certain by running them with trace active, and review the spooled trace output for its call flow detail.
