Library /sys$common/syshlp/dbg$uihelp.hlb DEBUGUI, disabled_vms_cmds  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The following table lists the debugger commands that are not available
  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-entry prompt, or when the debugger
  executes a command procedure containing any of these commands.
