I do not need the cpyfrmqryf they are just Debug tools, they are commented out,
I an saying that they work fine but with them not there there RPGiV program
does not read any records, as if nothing was selected, I think it may somthing
to do with invocation levels, but I have never had a problem like
this in the past.

Subject: RE: OPNQRYF does not seem to be working
Once you cpyfrmqryf are at the end of file and once you reach end of file,
you cannot re-position the cursor. Why do you need the cpyfrmqryf? It is
best not to use this. If the RPG does not update and you need the cpy for
down stream processing, run the RPG first. The cpyfrmqryf will reposition
and copy correctly after the RPG ends and closes the file. To run the RPG
after the CPYFRMQRYF the cl must close the file, but then you lost the
opnqryf results. A catch 22. If your RPG is not updating you can also
close the qryf, override to the qtemp file and run your RPG. No share is
involved and you can get rid of that. Now for the killer, When you need a
copy of the file and need to update the file, have the RPG output the
original record to the qtemp file as you process but before you update any
fields. This output replaces the cpyfrmqryf and increases performance. You
must first create the qtemp file though. CRTDUPOBJ with DATA(*NO) works
great, once you have the library name. Use RTVOBJD *libl/objname *file
rtnlib(&lib) to get your library's name. I wish that IBM would change the
EOF indicator and allow you to reposition the file cursor after the
cpyfrmqryf. Though the above suggestion does out perform processing the
opnqryf twice.

It is selecting no records in the RPG IV program (LBK0UPR).
If the commented out CPYFRMQRYF statements are run the data is selected
correctly in those files. Ihave tried using POSDBF
It does not help.
I have been through the archives and others are hinting at these problems.
The access paths were already shared open and i have tried removing the
OVRDBF commands none of it seems to make a diffrence. Am I going Mad. I
have used OPNQRYF much in the past, but with RPG III or 400 whatever
Anyone solved this
