To use this here version of Runback, you must do the following:

1) Add the file MOUNTLIST-ENTRY onto the end of your devs:Mountlist
file. Use a text editor or use the JOIN command.

2) Copy the file NULL-HANDLER into your L: directory.

3) Give the command MOUNT NULL:, preferably in your startup-sequence.

4) And of course put the file RUNBACK (the program itself) in your C:
directory or somewhere else where it'll be handy.

4.5) The other two files (null-runback.c and Paul.h) can be ignored.

Once you do this, you will be able to use the Runback command just
like the Run command. Any CLI command you give after the word Runback
will run in the background. The difference between Runback and Run is
that no output will be able to be written to the cli window it was
started from. Runback is generally used for programs that wouldn't
want to send any output there anyway. Run is not suitable for such
programs because it always leaves them the chance to write something
out if they want to, and this means that until the runned program
quits the CLI window it was run from cannot close. Or if you use Run
> NIL: sometimes it can close, but then if the program DOES try
to write something to it ...  blammo, you're toast.  Runback makes it
impossible for the program being run to hold the window open, and
makes it safe for it to try.

The differences between this version of Runback and older ones are:
it's quite small (820 bytes), it's pure and can safely be made
resident for speed, it doesn't work without the NULL: device, and it
lacks the feature of a -delay option. I'll add such if anyone asks me
to.

This Runback is by Paul Kienitz.  I can probably be reached on
