GO(OPCS)		Optical Printer Control System		GO(OPCS)

    NAME
	go  - Move motors some distance or to new positions

    USAGE
	go  [chans] [distance[,distance,...]]
	go  [chans] [>position[,>position,...]]

    EXAMPLES
	go d -10            # channel d goes -10 steps from where it is
	go efgh >0          # channels EFGH go TO position 0
	go efg 120,130,>0   # e goes 120, f goes 130, and g goes TO 0
	go ef 120           # ef go 120 steps from where they are

    DESCRIPTION
	Mostly for moving 'positioning' motors such as zoom, follow-focus,
	etc. This command allows you to run motors in incremental or to 
	absolute positions, allowing accurate control of motor positioning.

    GOTCHYAS

	1. When using GO to move shutter channels (cam, pro), their frame
	   counters will NOT be affected; counters are in frames not steps.

	2. Using GO on channels with interpolations configured are handled
	   specially:
	   
	   2a. When channels are SLAVED together with INTERP (e.g. focus (f)
	   slaved to zoom (e)), specify both channels to GO for them to
	   move together, one slaved to the other. Otherwise they will
	   be moved separately. e.g.

	    go ef 12000     #'e' moves 12000 steps, and 'f' will move
                            #    (some distance) to maintain focus.

	    go e 12000      #'e' moves 12000 steps. 'f' wasn't specified,
                            #    so it WON'T MOVE. (no follow focus)

	    go f 12000      #'f' moves +12000 steps (e does not move)

	    go f >-30000    #'f' moves to position -30000 (e does not move)

	   2b. Alternatively, with a single channel interpolation (such as a fader),
	   moving the channel with relative positions will move the channel
	   in STEPS. Only when positions are specified with absolute positions
	   (e.g. >170), interpolations will be used. e.g.:

	    go d >170       #'d' moves to 170 DEGREES. Absolute positioning
                            #    of the fader always works in DEGREES.

	    go d 10         #'d' moves 10 STEPS. Relative positioning
	                    #    of the fader always works in STEPS.
