csh setenv problem

[Lenny Saaf]

I want to execute a csh script and set some variables for use in the
parent shell.  As I understand it, the script in the file is executed
in a subshell, so I think I have to "export" any csh variables I set
in the shell script.  That is, use setenv as opposed to set.  Well, I
can't seem to get it to work.  The shell script file looks like this:

# csh script
# filename is testscript
setenv FOO 'bar'
echo $FOO
# end

The result:

[1]% chmod +x testscript
[2]% testscript
bar
[3]% echo $FOO
FOO: Undefined variable.



What am I missing?
