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.

Subject: Re: Screen Refresh
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.
