%QS
|
With this command, you can display multiple screens simultaneously.
%QS
causes the next screen I/O not to be
executed. The corresponding output screen is kept internally until the
following I/O, when it is displayed together with the next screen. Therefore
%QS
only makes sense if the second output screen is
a window, that is, if it does not entirely overlay the first screen that was
suppressed with %QS
.
Example: You can suppress the output of a screen A with
%QS
; the next screen B is a window which partially
overlays screen A (perhaps a help window for one of the fields on screen A);
with the next screen I/O, the window B and the "underlying" screen
A are displayed simultaneously.
A %QS
command only applies to the
subsequent screen.
Note:
As %QS
reduces the number of screen I/O
operations, it also improves performance.
