best == only

Finding all the places and ways that Relative Mode (which should be a simple
concept) affects operation from reading the code is non-trivial.

What does PREVIEW (CMND = 2) do ?

How to know the distinctions between

	scanPASM_Start_Pos (REC_SCAN_AS_ST)
and
	scanPASM_Prior_Pos (REC_SCAN_AS_BS)

as the PnPP fields are not documented ?

Also undocumented :

       Before/After Scan PVs/CMDs (looks very useful)
       DPT
       PnPP
       PnCV
       DnNE
