Re: Write to IFS text file

All,

Pardon me if this sort of drags on; I figure when I get (or figure out)
the answer to this it'll be a great teaching moment.

I have an RPGIV program that reads invoices and writes checks; a logic
cycle program breaking on vendor number. Simple enough. It needed to be
modified to produce a text file that our bank will use to prevent check
fraud (we got hit recently).

I've used Scott Klement's wrappers (i.e. "RPG And the IFS") to read/write
to the IFS and never had a problem - they're wonderful. I convert the
source to ILE-RPG, get it into freeform, and remove the logic cycle
processing. The code that executed on the vendor break I put into a local
subprocedure.

However, after executing the program, the text file on the IFS had only
one record in it, which corresponded to the last vendor in the input file.
I put it into debug to prove the write statement in the procedure executed
for each vendor break. Spent days trying to figure it out to no avail. In
an act of desperation, I tested putting the code into a subroutine and
moved the local declarations back into the main procedure. It worked like a
charm; all records were written. It was as if when the code was in a
subprocedure, all the writes were stomping on the data that was already
there with the next write to the text file overwriting what was written
previously.

So, what's the explanation for the difference?
