Yes.  In the DDS source for your screen, use the FRCDTA keyword.  This
causes the screen be displayed immediately.  (Normally, the output isn't
displayed until you request input, FRCDTA makes it display immediately)

Then, when you want the screen to appear, do a WRITE to the screen record.
That'll cause it to display the screen & return control to your program
immediately.  You can then do more processing while the user reads your
screen..

An alternative to using FRCDTA is the DFRWRT(*NO) option of the CRTDSPF
but I do NOT recommend using DFRWRT(*NO) for two reasons:

   1) Using DFRWRT you affect all records of the display file, instead
        of just the one you need.  That affects performance.

   2) You have to remember DFRWRT every time you compile the display,
        and everyone else who compiles it has to know as well. That
        makes maintenance more difficult.

You do not have either of these problems if you use FRCDTA.
