SET DISPLAY UPDATE STATE (PHOP,WSOP,*,*)

Purpose

Use Set Display Update State to set the deferral state and modification mode for the specified workstation state list.

Possible deferral modes include: AS SOON AS POSSIBLE, BEFORE NEXT INTERACTION GLOBALLY, BEFORE NEXT INTERACTION LOCALLY, AT SOME TIME,and WAIT. Possible modification modes include: NO IMMEDIATE VISUAL EFFECTS, UPDATE WITHOUT REGENERATION, and USE QUICK UPDATE METHOD.

These settings determine when pending updates are processed for display on a workstation and how the workstation performs the modifications. For an explanation of the abbreviations and modes, see The graPHIGS Programming Interface: Understanding Concepts. For specific workstation information, see the section on "General Output Facilities" in The graPHIGS Programming Interface: Technical Reference. Quick update methods are discussed in The graPHIGS Programming Interface: Writing Applications.
