KEYDEF(OPCSDEFS)        Optical Printer Control System       KEYDEF(OPCSDEFS)

    NAME
        keydef - This command has been made obsolete by KEYFUNC(OPCSDEFS)

    USAGE
                            ----- KEY DOWN -----   ----- KEY RELEASE -----
        keydef [function]   [port] [mask] [test]   [rport] [rmask] [rtest]

        [function] is the name of the keyfunction to redefine. See the list
        of names below.

        The 'KEY DOWN' port/mask/test definitions define the IBM PC port
        to monitor which will invoke the named function.

        The 'KEY RELEASE' port/mask/test definitions define the IBM PC port
        to monitor to determine when the key is released. This can optionally
        be defined to monitor a 'continuous' switch, so that the motors will
        stop when the continuous switch is released:

                keydef  profwd1  3bd 40 40  3bd 41 00

        The above monitors port 0x03bd for the 0x40 bit. When set, the motor
        will run until the 0x40 and the 0x01 bit of the same port are zero.
        In this case, the 0x40 bit is probably the invoking button, and the
        0x01 bit is the 'continuous' switch; if on, the motor will run until
        the continuous switch is turned off, even if the 0x40 bit is released.

    DESCRIPTION
        This command allows the user to redefine the keyboard keys while the
        KEY(OPCS) command is running. The user can actually assign the 
        operations to not only any keys on the keyboard, but any bit on
        any port on the IBM PC.
        
        This allows for external buttons to control bits on the parallel port
        (or whatever ports are available) and thus control any of the functions
        supported by the KEY(OPCS) command.

        The following is a list of all functions the KEY(OPCS) command 
        currently supports. These names are used in the KEYDEF(OPCSDEFS)
        commands that appear in the OPCSDEFS.OPC setup file as a default:
