No $watch variable set

[Krister Bruhwel]

I'm trying to use command line args in a script.  I'm using the 
following code:

#!/usr/local/bin/python
import os, sys
print sys.argv[0]

It works fine on the Linux machine, but when I move it to a HP
machine I get this error message:

No $watch variable set.

I'm new to Python and I don't know what to do about it.
I have searched the web and no luck.
Can anyone help?

Thanks,
Krister
