Assigns the debugger's abort function to another Ctrl-key
    sequence. By default, Ctrl/C does the abort function.

                                   NOTE

       This command is not available in the VSI DECwindows Motif for
       OpenVMS user interface to the debugger.

    Format

      SET ABORT_KEY  = CTRL_character

1  –  Parameters

 character

    Specifies the key you press while holding down the Ctrl key. You
    can specify any alphabetic character.

2  –  Description

    By default, the Ctrl/C sequence, when entered within a debugging
    session, aborts the execution of a debugger command and
    interrupts program execution. The SET ABORT_KEY command enables
    you to assign the abort function to another Ctrl-key sequence.
    This might be necessary if your program has a Ctrl/C AST service
    routine enabled.

    Many Ctrl-key sequences have predefined functions, and the SET
    ABORT_KEY command enables you to override such definitions (see
    the OpenVMS User's Manual). Some of the Ctrl-key characters not
    used by the operating system are G, K, N, and P.

    The SHOW ABORT_KEY command identifies the Ctrl-key sequence
    currently in effect for the abort function.

    Do not use Ctrl/Y from within a debugging session. Instead, use
    either Ctrl/C or an equivalent Ctrl-key sequence established with
    the SET ABORT_KEY command.

  DBG> SHOW ABORT_KEY
  Abort Command Key is CTRL_C
  DBG> GO

      <Ctrl/C>
  DBG> EXAMINE/BYTE 1000:101000  !should have typed 1000:1010

  1004: 0
  1008: 0
  1012: 0
  1016: 0
      <Ctrl/C>
  %DEBUG-W-ABORTED, command aborted by user request
  DBG> SET ABORT_KEY = CTRL_P
  DBG> GO
       . . .
      <Ctrl/P>
  DBG> EXAMINE/BYTE 1000:101000  !should have typed 1000:1010
  1000: 0
  1004: 0
  1008: 0
  1012: 0
  1016: 0
      <Ctrl/P>
  %DEBUG-W-ABORTED, command aborted by user request
  DBG>

      This example shows the following:

      o  Use of Ctrl/C for the abort function (default).

      o  Use of the SET ABORT_KEY command to reassign the abort
         function to Ctrl/P.
