| Range | 0 \~ 3 |
System Variable Value:
0: no multithreaded processing; restricts regeneration and redraw processing to a single processor.
1:regeneration multithreaded processing only; regeneration processing is distributed across two processors on a multiprocessor machine.
2: redraw multithreaded processing only; redraw processing is distributed across two processors on a multiprocessor machine.
3: regeneration and redraw multithreaded processing; regeneration and redraw processing is distributed across two processors on a multiprocessor machine.
When multithreaded processing is used for redraw operations (value 2 or 3), the order of objects specified with the DRAWORDER command is not guaranteed to be preserved for display but is preserved for plotting.
