It is possible to force all segments within the WDSS on a particular
workstation to be re-drawn by calling the routine
Re-draw SeGments on WorKstation:
CALL GRSGWK(WKID)
The routine clears the screen, performs all deferred actions,
and re-draws all segments. All non-retained data is lost.
Possible reasons to re-draw all segments are:
- if a segment had been over-written or deleted and it is
desired to regenerate a clean image;
- if one wishes to remove all non-retained data,
system messages, etc;
- if, on this workstation, image regeneration is required in order to
display the effect of modifying a segment attribute, and implicit
regeneration is switched off.
The action of this routine differs from that of
Update WorKstation (GUWK), which may or may not re-draw segments
which have not been changed.
