Use CpyFrmQryF and output the selected
recs to a work file.  You can then do a Dspfd on the work file.

Subject: OPNQRYF Observation


I am a bit behind the times, learning how to use things for the first time 
about the time everyone else who ever learned it is moving on to other 
technologies.

Suffice it to say that last nite I wrote my first CL that had an OPNQRYF in 
it.
I thought the difficulty was that you cannot concatenate a numeric variable,

but I needed to *EQ a numeric value with a numeric field, and you can't 
compare alpha to numeric, then when I finally got the darn thing to compile
& 
run without any errors, it came up with zero data.  Come to find our hours 
later my choice of test data was in fact empty ... occasionally AL MAKES A 
MISTAKE.

Since the OPNQRYF selection of data was new software &
since the RPG program the data was being fed to was also a new program &
since I did not realize that there was in fact no data that met the original

test conditions

something that would have been very useful to me while trying different test

conditions would have been some piece of code between the OPNQRYF statement 
and the CALL RPG statement
to SNDPGMMSG or something that identified the number of records found by 
OPNQRYF
and I mean to a log that I can read after I have exited the program, not
just 
on bottom of screen while it is running.
I was doing tests with CHGJOB cranked up to LOG(*YES) and seeing tons of 
other stuff cluttering the picture.

This is now an academic question since by the end of the evening my new 
software was working satisfactorily.  It is not as elegant as I would have 
liked, but it works.
