RPG Cycle doesnt work, then it does

Back again, from late 2024.



I appreciate all the responses to my original issue from late last year.
I've tried all of them to no avail.
I have to try being more specific in what is being done here, in the hopes a
light will go off for someone.



We have a process which generates RPGLE source code which uses the RPG
matching records function.
The files being matched are files generated using the OPENQRYF command. The
Open Query files appear as f specs in the RPGLE source code as primary and
secondary files.

The necessary overrides are all done appropriately before the source code is
generated and compiled.

While I have been primarily testing and debugging this process
interactively, I've also tested it in batch mode. The results are the same.



When the generated program is called (BTW the program object is in QTEMP),
only the INZSR is executed. The two primary and secondary files are both in
status 0011 (end of file on a read) and I know this because I have the INFDS
structures for both. So, LR is set on and nothing in the C specs gets
executed.

Since I am testing this interactively and using debug, as soon as the first
execution ends I can call up a command line and issue the very same call
command to the same generated program, as it is in QTEMP and all the
overrides are intact.
When I do that, the two input primary and secondary files have data in them
and the program executes correctly. LR is not set on until both files have
actually reached end of file.



So, how/why would the two input files, which are the results of using
openqryf, apparently NOT have data in them, and then suddenly have data in
them when the program is called from a command line?



BTW, I modified the process to call the generated program back to back and
both executions result in the apparent empty primary and secondary files.
But even then I can call the program from the command line, in the middle of
the debug session, and it works.



Any ideas?



Warm Regards and thanks in advance
