Re: Did OPNQRYF give out an empty record set?

Antonio,

To add to Carel's solution, there are messages sent by CPYFRMQRYF. CPC2955
is sent when there ARE records, CPC2957 when there are NOT. You could
RCVMSG for one of the other and branch from there.

Vern, answering your question on what I'd like to do differently...
In the CL I have a display file where I introduce some fields that will serve
as "filter" for the data being processed.
Sometimes the user makes some mistake, ans as result no data is pulled
from the
OPNQRYF.
I'd like to pop-up a message or a window warning the user and asking for new
filter data, before the RPG pgm will run without any results.

Thanks to everybody who answered.
Antonio
