Well, actually, what I wanted to do was to perform a read on a display
file and continue the execution of a program _even_ if there is no input
available (if there is - process the input)... For example, one would
want to do such a thing if one would want to display a running (or
should I say `ticking`?) clock to a user _until_ the user presses, for
example, PF03. I didn't know that was possible (because all programs I
had seen didn't have any automatical refresh - they usually put it on
PF05, like WRKACTJOB) until I saw one CL program which did that. I did
RTVCLSRC (or whatever stands for `Retrieve CL Program Source Code`) and
saw that all it does is one RCVF WAIT(*NO). I started looking for a
similar function in RPG... And couldn't find it... Still haven't found
it... Any ideas?

                     Thanks in advance, Juris.

P.S. Could someone of you give a brief description of panel groups?
