RE: Can't See the Difference

You're, of course, absolutely right as regards the copy books. In my haste
I overlooked them.

As for the 'simple but complete' part, I did not want to inadvertently
remove code that, while it seemed innocuous to me, might have contributed to
the problem.

But I must have been having a "bad hair day" Tuesday as the program is
working as intended today - with nothing but a re-compile. Was I debugging
the correct code on Tuesday? I was awfully sure that I was ending and
re-starting STRDBG between around the re-compiles the other day, but perhaps
I wasn't as careful in this or some other regard as I intended. Whatever
the reason, I erred on Tuesday.

I do appreciate your offer to troubleshoot my problem when I'm sure you have
plenty of your own work to do. Tell Alex 'Hi,' and I promise to buy more
sausage as a small way to make amends.

hi Jerry,

I guess when I said "Simple but complete program", I was expecting you to
strip the program down to just the parts absolutely needed to make a
runnable program that demonstrates the problem. I wasn't especting you to
post the /entire/ program...

Plus, and I thought I made this clear, it needs to be something I can load
and run on my system. Without that, I really can't troubleshoot it. The
code you posted requires multiple copy books that I don't have on my system,
so it can't be compiled.

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.
