Well, here is a practical reason to not have every rc variable
exported. I have argued this on aesthetic grounds before.

It would be nice to have some sort of 'local' declaration for variables,
such that they aren't handed to exec()ed programs, but I don't think it
should ever be the default. Almost all of my variables are ones I want
to export.

Maybe someone should write an xargs-like program for the environment,
:-)

'Arg list too long' is actually 'Arg list or environment too long',
because most Unixes have a limit on the total argument list + environment
size that execve() will handle. Ultrix just has a somewhat lower limit
than other systems (I think SunOS has really cranked it up, for example).

Rc puts everything in the environment and most systems have a limit
on the size of the environment...

I have just dicovered a strangeness running rc1.3b on a decstation
ultrix 4.1:
allman = `{ man -nrsp '.*' }
This assigns allman the names of all manpages available, in short, a very
large value (>250KB).
After doing so, any external command issued, with or without arguments,
gives the error message
'<prgname>: Arg list too long'
so I can't find out what happens.
Is this a bug in rc or ultrix ?
Malte.
