Hi.

Here is the result of running on an AIX system to which I have access:
Code:
#!/bin/sh

echo
echo " System name, release, version:"
uname -s
oslevel

echo
echo " .cshrc:"
cat $HOME/.cshrc

echo
echo " Script s1, and results:"
cat s1
echo
./s1

echo
echo " Script s2, and results:"
cat s2
echo
./s2

exit 0

producing:
Code:
$ ./s0

 System name, release, version:
AIX
5.1.0.0

 .cshrc:
#ident  "@(#).cshrc     1.2     00/05/01 SMI"
echo " .cshrc invoked, version 2010.04.21."
umask 022
set path=(/bin /usr/bin /usr/ucb /etc .)
if ( $?prompt ) then
        set history=32
endif


 Script s1, and results:
#!/bin/csh

echo " Hello, world."

 .cshrc invoked, version 2010.04.21.
 Hello, world.

 Script s2, and results:
#!/bin/csh -f

echo " Hello, world."

 Hello, world.

So this works as I expect it.

I see that on AIX, the command which is itself a csh script. The first few lines are:
Code:
#!/usr/bin/csh -f
set prompt = "% "
if ( -f ~/.cshrc) then
        source ~/.cshrc
endif
...

If it's the same on your system, then I think you have the reason for the behavior you have seen ... cheers, drl
