I am trying to write a program that can be called from another program and
pop up a window with a subfile in it. I've gotten every thing to work
except I cant keep the original screen from being redrawn when the second
program is called. Has anyone been able to do this?

You can firstly try using an OVERLAY Keyword in the original Screen or
another possible solution is using 'Share Open PAth' on the CRTDSPF
cammand.

Loomup the ASSUME keyword. If I understand your problem
correctly, it will be what you are after.

In the display file with the window you need to create a dummy
record that has the keywords KEEP and ASSUME. The record must
also have a at least field, a text string will do the job. Hope
this helps.

You need to add a dummy record format to the display file. It needs to
have the ASSUME keyword specified in it:

A R NULL
A ASSUME
A 1 2' '

You never actually use the record format - it just needs to be there.

That's the way to do it... but when you call the second program that
open the window... the background screen will reappear with it.
DSPFs are in SHARE(*YES) for just one open.

Have you a solution for that ?

You need to overwrite the background of your window subfile with blanks
so that the previously opened display file image is obliterated and will not
confuse things when the subfile is output.

Do this by writing a format with blank constants.

It used to be true that you needed to pad all of the blank spaces with
actual blanks, but if you use the window keywords in your DDS you no
longer have to do this. You code it just like a regular screen.
