I found the scripts for B for Bourne shell and rc somewhere, but at
that time I only downloaded the Bourne version, which I still have,
and now I don't seem to find the place I snarfed them from. I have
gone through the Bell Labs FTP site, but I wasn't able to find them
there.

Where can I find an rc version of B that will work under Plan 9? The
Bourne shell version I have makes use of a temporary file to send
commands to sam. The file is named after the user and the DISPLAY
variable. I figured that the rc script available was for Unix systems,
too. Is it possible to use the same script under Unix and Plan 9? I
find that strange.

the full kit includes /rc/bin/B which (unsurprisingly) works under plan 9.
plan 9's sam puts one end of a pipe in /srv.
the B.rc in the unix plan 9 distribution is not the same as the plan 9 version.
i don't know whether the four diskette version includes /rc/bin/B.

that reminds me: new plan 9 users
might not be aware of the following way to use sam.
it works on plan 9 but also on some unix systems.

in my window system startup file,
i typically create one window of significant size in which i run sam.
that remains on screen until i log out (subject to `Hide' in 8½ or 9wm).
as i wander about the system in other windows, i use the B command (see sam(1))
to throw files into it for editing.

on slow terminals, the single sam instance can be invoked as sam -r $cpu.
using this method, you are also rarely bothered by windows containing
the remnants of an instance of sam.
