Setting shell prompt variable different from .cshrc

[Martin J. Buckley]

I would like to create an applications that uses a shell as the primary
interface.  A separate window or terminal session would be maintained
for this application.  To keep things simple, the only designator that
this session serves a special purpose would be the command prompt.

I expected this to be easy, but have been unable to successfully
implement this under ultrix.  Have tried all of the following to no
avail:

1) creating a cshell script that sets the environment variable "prompt" to
the desired value and invoke a subshell via "csh -s -f"

2) created a shell script that invokes a subshell via 
	"(export prompt;prompt=value;csh)"

3) created a cshell that modified HOME to point to a directory that has
a .cshrc with prompt set and invoked a csh.

None of these worked on Ultrix.  I would appreciate any suggestion on what I 
am doing wrong and/or on how to accomplish this.

Thanks

None of these things worked.
