[X-Unix] BASH problem?

[Russell McGaha]

Folks;
	In an effort to start learning Bash I change my shell from Tcsh to 
Bash, but that's caused a problem.  I've a script that runs nightly to 
pull and build Mozilla, the script is a Tcsh script with a first line 
of "#!/bin/tcsh -x".  Now I THOUGHT, that line told the 'system' to run 
that script under Tcsh; but with my shell set to Bash, I get all kinds 
of Bash errors on the first lines of the script and the script doesn't 
run.  I've tried running "do script with command "/bin/tcsh;source 
MozScript1d.txt;" " from an AppleScript to invoke Tsch first, and then 
run the script; but all though Tsch gets invoked my scripts doesn't.
	Anyone know what I'm doing wrong or how I can correct this?

TIA
Russell
