output-option

    Specifies an output option to be enabled or disabled. Valid
    keywords are as follows:

    LOG          Specifies that debugger input and output be recorded
                 in a log file. If you specify the log file by
                 the SET LOG command, the debugger writes to that
                 file; otherwise, by default the debugger writes to
                 SYS$DISK[]:DEBUG.LOG.
    NOLOG        (Default) Specifies that debugger input and output
                 not be recorded in a log file.
    SCREEN_LOG   Specifies that, while in screen mode, the screen
                 contents be recorded in a log file as the screen is
                 updated. To log the screen contents, you must also
                 specify SET OUTPUT LOG. See the description of the
                 LOG option regarding specifying the log file.
    NOSCREEN_    (Default) Specifies that the screen contents, while
    LOG          in screen mode, not be recorded in a log file.
    TERMINAL

                                           NOTE

                       This parameter is not available in the HP
                       DECwindows Motif for OpenVMS user interface
                       to the debugger.

                 (Default) Specifies that debugger output be
                 displayed at the terminal.
    NOTERMINAL

                                           NOTE

                       This parameter is not available in the HP
                       DECwindows Motif for OpenVMS user interface
                       to the debugger.

                 Specifies that debugger output, except diagnostic
                 messages, not be displayed at the terminal.
    VERIFY       Specifies that the debugger echo, on the current
                 output device, each input command string that it is
                 executing from a command procedure or DO clause. The
                 current output device is by default SYS$OUTPUT (your
                 terminal) but can be redefined with the logical name
                 DBG$OUTPUT.
    NOVERIFY     (Default) Specifies that the debugger not display
                 each input command string that it is executing from
                 a command procedure or DO clause.
