Just for kicks and grins, I modified the program so that the $PostList
subprocedure is now a subroutine. Bear in mind that the subprocedure was
working in the original version (posted to code.midrange) but the subroutine
was not working.
After making the change, both sections are now working. I made absolutely
no change to the logic or code, except making $PostList a subroutine.
STRDBG show that the program is passing through the $EditA subroutine
testing each element of the subfile.
There are still other problems with the program, but those are definitely my
errors.
Even more weirdness. I saved the original code before making the change
noted above. I restored it, re-compiled, and now it's working! I swear on
my oath as an RPG programmer that this is the original code of which I
complained on Tuesday! I can't even chalk this up to having a "senior
moment." Something is obviously different, but what is beyond me.

Okay, I've uploaded the code for the program, display file and its only
physical file at

Sorry for the delay, but Wednesday is my day off.

Hi Jerry,
I suspect that the problem isn't in the code you posted, but rather is
somewhere else in the program (that you haven't thought of.)
Could you post a simple (but complete) program that we could load and run
that demonstrates the problem? I realize that this is a bit more work than
just copy/pasting snippets from your code -- but if you can make a simple
program that only has the needed code, and doesn't rely on any external
files (since we won't have those) that reproduces the same problem, then
we'll be sure to have everything we need.
If I'm able to load/run the program on my computer, I'll be able to really
troubleshoot it. (Rather than just giving it a quick glance.)
That's about all I can offer.

I have code in two places in my program that loop through a subfile.
The code is essentially the same. The first set is in a subroutine
and the second set is in a subprocedure. The subprocedure set works;
the subroutine set doesn't. It's the latter that's got me puzzled
(obviously).
I have stared at this all morning and can't see any difference between
the two sets of code, but I've only got one eye and it's aged and
often blurry after staring at a terminal most of the day. Maybe
someone else can point out what is probably an obvious flaw that I
can't
see.
Subroutine code (not working):
IF #limit> *Zeros;
FOR x = 1 to #limit;
CHAIN x DTU020A;
IF %found();
(some code)
Subprocedure code (working):
IF #Limit> *Zeros;
FOR x = 1 to #Limit;
CHAIN x DTU020A;
IF %found();
(different code)
In the interest of full disclosure: the definitions of the variables are:
D #Limit S Like(rrna)
D X S Like(rrna)
And rrna is the relative record number of the subfile record
(DTU020A). The debug of the subroutine code on the CHAIN 'x' has a
value of '1'. After the IF %found(), the subroutine bypasses all of
the "some code" stuff. The FOR loop runs for as many records as there
are in the subfile; it's the CHAIN in the subroutine that doesn't find
the
subfile record.
