Terminal: How to log and keep SYS$OUTPUT

The Question is:

1.  how can sys$output be redirected to a file instead on the screen
and then switched back?

      or

2.  How can I capture the scrollback on an x-terminal
(VAXstation 3100) to a file?

thank you.

The Answer is:

1.  You can't other than by SET HOST/LOG.

2.  Type the command CREATE file.txt.  Use the mouse to select the lines
    in the scrollback buffer you want to copy, then click on MB2, then
    press ctrl-Z.

    capturing arbitrary output...

    As long as you don't need to see the output on the terminal, it is
    possible to redirect the output of an arbitrary sequence of commands
    into the same file. Use:

    $ @TT/OUTPUT=filespec
    _$ command1
    _$ command2
    	...
    _$ command-n
    _$ EXIT
    $

    Note that during the redirection, your prompt gets a leading "_" and
    you won't see any output.

    It shouldn't be too hard to add a "capture output" menu command to
    DECterm, I wonder if it's worth asking (does Eric Osman read this
    conference?)

DECterm includes a print to file capability.  It is located under the Options
pull down menu.  Combined with the auto print mode and there ya go.

    You can also write code based on SYS$EXAMPLES:LOGGER.C.  It uses the
    pseudo terminal driver and lets you do what you want with the data!
