The following commands are disabled in the debugger's DECwindows
    Motif interface. Many of them are relevant only to the command
    interface's screen mode.

    ATTACH             SELECT
    CANCEL MODE        (SET,SHOW) ABORT_KEY
    CANCEL WINDOW      (SET,SHOW) KEY
    DEFINE/KEY         (SET,SHOW) MARGINS
    DELETE/KEY         SET MODE [NO]KEYPAD
    DISPLAY            SET MODE [NO]SCREEN
    EXAMINE/SOURCE     SET MODE [NO]SCROLL
    EXPAND             SET OUTPUT [NO]TERMINAL
    EXTRACT            (SET,SHOW) TERMINAL
    HELP               (SET,SHOW) WINDOW
    MOVE               (SHOW,CANCEL) DISPLAY
    SAVE               SHOW SELECT
    SCROLL             SPAWN

    The debugger issues an error message if you try to enter any
    of these disabled commands at the command prompt or when the
    debugger executes a command procedure containing any of these
    commands.

    The MONITOR command works only with the DECwindows Motif
    interface (because the command uses the Monitor View).
