RE: Screen Refresh -- MIDRANGE-L

        Thanks for the response. But, still I have not been able to get the
desired results. Basically my requirement is that when I         
        do EXFMT(or SNDRCVF) for the display file, and then for 2 minutes I
don't do anything, then the control should return back to  
        the program and accordingly take proper steps(based on whether it
was a time out or whether the user entered something        
        within the stipulated 2 minutes) . I am using V4R1.    
 
            Am I  going wrong somewhere?

Isn't INVITE a record-level keyword?

Sounds simple enough and the example in the CL programming manual
SC41-5721-02    looks pretty basic but something's not working.  When I
press Enter or any function key, it doesn't put anything in the data queue.

The display file was created w/ the DTAQ parameter and DFTWRT(*NO). 
I've created the data queue prior to calling the program. 
I write the screen - WRITE RECORD 
Then, I call the QRCVDTAQ program to receive the data queue with a wait time
of 120. 
When I press Enter or any function key, it just stays at the screen and
nothing happens until the 120 seconds expires.  Nothing gets put into the
data queue either.

What am I missing?  I don't see if from the manual.  The only thing it
mentions is INVITE but when I put that in at the file level, I receive an
error message.

Yes. Override the display file to a data queue and then read the data 
queue in your program. You can specify a timeout value for the data 
queue. If the user presses Enter or a function key you will be able to 
tell from the data queue contents and you can then read the display 
file. If the data queue read length is zero you know it's timed out and 
you can refresh the display or whatever.
