CMDLINE(OPCSDEFS)      Optical Printer Control System         CMDLINE(OPCSDEFS)

    NAME
        cmdline - set the OPCS command line editing style

    SYNOPSIS
        cmdline [dos|editor]

	    dos    - Old MS-DOS style command line editing (F1, F3, F5..)
	    editor - New interactive command line editing with history

    EXAMPLES
        cmdline dos     -- old style command line editing (pre-K200)
        cmdline editor  -- enable new interactive command line editor

    DESCRIPTION
        New in K200 and up, this command lets you change the OPCS command
        line to respond to more interactive text editing on the command
        line, allowing insert/delete, command history, line editing.

        'cmdline dos'
        -------------
        This is the old editor style, which doesn't support interactive
        line editing, and is basically whatever MS-DOS command line editing
        provides.

        'cmdline editor'
        ----------------
        This is the new editor style, which supports more interactive line
        editing that people are generally familiar with in interactive
        text editors like MS-DOS 'EDIT', NOTEPAD, etc. Edit keys supported:

             Up Arrow -- previous line in command history      (^P)
             Dn Arrow -- next line in command history          (^N)
             Lt Arrow -- move reverse one char on current line (^B)
             Rt Arrow -- move forward one char on current line (^F)
            Backspace -- backspace and delete                  (^H)
               Delete -- delete character                      (^D)
                 Home -- move to start of current line         (^A)
                  End -- move to end of current line           (^E)
            Ctrl-Home -- jump to top of command history
             Ctrl-End -- jump to bottom of command history (current line)
            Ctrl-Left -- word left
           Ctrl-Right -- word right
                   ^K -- clear to end of line
                   ^U -- clear current line (hit again to 'undo')
		   ^V -- enter next character literally
