Re: Stale Window Background

[David Keck <DavidKeck@xxxxxxxx>]

Carel,
      KEEP is only needed in the scenario where PGMB's display file is
closed after each call.  It prevents filcker when returning to PGMA's
screen.  It has no effect when leaving PGMB's display file open.  USRRSTDSP
has always seemed obscure to me.  As best I can tell it improves system
screen handling performance under certain circumstances, but has no effect
on the appearance of the final rendered screen.  Including USRRSTDSP in
PGMB's display file would not help screen performance because that program
only issues a single record format, and calls no other programs.  Whether
including it in PGMA's display file would improve performance is unclear to
me.  I have read the manual and many explanations of USRRSTDSP, but none
ever left me with a comfortable understanding.  Anyway, unless you're in a
dial-up environment I doubt you'd ever notice it's benefit.

Thanks, Dave
