;XXXSCN is routine to apply mode specific SCAN defaults
;	called with I=scan spec to fix up
;XXXNXT is routine to get next object in O
;	called with O=last thing (-1 to start)
;	skip return with next thing in O, non-skip when done
;XXXINC	is routine to handle computation of incremental statistics
;XXXPRF	is routine to print performance information for the mode
;XXXSET	is routine to verify thing in O is valid
;	skip return if thing good, non-skip if not
;XXXMAM is the routine to handle /MAP (Map Alternate Mode)
