LOGCOUNTERS(OPCS)     Optical Printer Control System     LOGCOUNTERS(OPCS)

    NAME
        logcounters - configure if cam/pro counters should be logged

    SYNOPSIS
        logcounters [on/off]

    EXAMPLES
        logcounters on      # log files will contain counter info
        logcounters off     # DON'T put counter info into log files

    DESCRIPTION
        When LOGCOUNTERS is on, and a LOG(OPCS) command is logging out to a
	file or line printer, the motor positions are logged along with each
	line the operator types. The positions are entered into the file as 
	comments, so when executed, the position information is ignored.

	The format of how the counters are logged is configured with
	LOGFORMAT(OPCSDEFS).

	This information may be necessary for debugging purposes, but in most
	cases just 'clutters up' an otherwise easy to read file, and it may
	be desirable to leave this setting off when logging to files.

    BUGS
        If the operator uses ALLSTOP during command logging, it would be
        unwise to later execute the log file as a run script without making 
        the proper modifications to the commands that were interrupted. Here 
        is a sample log with a command that was interrupted:

            #  1:1   0(0'0)         20(1'4)       CLOSED 0   
            cam -120

            # ### OPERATOR HIT ALLSTOP KEY
            #  1:1   0(0'0)         18(1'2)       CLOSED 0   

        Note the camera counter now reads 18 instead of -100. Because the
        command was interrupted, it never got to finish shooting. This
        could cause confusion later if this log were executed as a RUN script,
        and commands that followed used absolute positioning (cam >134).
        The command cam -120 should then modified by hand:
        
            cam >18    or   cam -2

        ...to reflect the command as it was actually executed.
