This is actually not the same “pause type” as PAUSE_ON/PAUSE_OFF, (despite the fact that the docs make no mention of this). PAUSE_SET is like “Dev Mode pause” while PAUSE_ON/OFF is more like “ESC key pause” but w/out the popup menu.
Caveat emptor: Unless something has changed in FS24 in the last couple months, ofc… I tested in an earlier release and it seemed same as FS20.
