I am writing a perl script which I must, for the time being,
integrate with some csh scripts. For this I need to be able
to examine a shell variable created in a csh parent script,
and I would also like to be able to create a csh variable
from within the perl script, although the latter might be 
asking too much since I don't even know how to do it from
within a csh script. Needless to say I am a rank amateur 
at perl and the solution might indeed be trivial but after
two hours of hacking I haven't managed to trip over the 
answer.

Yes I do realize that I could use environment variables
using $ENV{'xxxx'} or modify the calling script to pass
the variables as command line arguments, but I would 
much rather simply integrate my perl script without 
changing the csh script which invoked it. Any suggestions?
