How can previous screen be retained

PGMA displays a full screen.
PGMA then calls PGMB which displays a window.
The window displays with a dark background, and PGMA's display is erased. I need to see PGMA's display with the window on top.

What should be done to achive this?

While compiling the DSPF there is an default parameter Restore display . . . . . . . . RSTDSP *NO. Change this as RSTDSP *YES. By doing this we can achieve the above requirement.

Is that enough Razuk?

Added to the above information we can create dummy records format with Assume keyword. This will help to retain previous screen.
A R DUMMY ASSUME
A 1 2' '
