running csh scripts from an sh shell in System V

[Dr. Scump]

In System V  (specifically AT&T System V/386 Release 3.2.2):

If my current shell is sh, how can I run a self-contained csh script?
In BSD, I can say "#!/bin/csh" as the first line, and the script
will run as csh regardless of the invoking shell.  In either BSD or
System V, I can run an sh script regardless of the shell it was invoked  
from by using ":" as the first line.  How do I do the equivalent of
"#!/bin/sh" in System V?  Can't find it in TFM...

Objective: I want to have a csh script that will run in any (BSD or 
SVR3) environment regardless of the user's current shell.

Thanks in advance.
