Function: To delete segment.
Segment function. Deletes a segment from all workstations.
Parameters

sgna (specified by user) (fullword integer)
The segment name selected when the segment was created.
Operating states
WSOP, WSAC, SGOP
Related functions
Create segment (GCRSG), Delete segment from workstation (GDSGWK), Set deferral state (GSDS)
Description
This function deletes the segment from all workstations. The segment name may then be reused by the application program.
The following actions are taken:
  • The segment name is removed from the list of segments at each workstation that contains it.
  • The segment name is deleted from the list of segment names in use in the GKS state list.
  • The segment state list for the segment is deleted.
Whether the segment is immediately deleted from the display of a workstation, or deletion is deferred, depends on the implicit regeneration mode for the workstation; this can be set using the function Set deferral state (GSDS).
