UNIX Shell Interaction

[Stuart Ford]

Howdy guys.

I'm currently trying to integrate a python script into an existing ksh script.

Could anyone tell me how to return a value to the calling script..

Example:

TEST_VAL=`ValidateData.py $FILENAME`


I have tried to assign a value to the variable via os.environ, os.putenv and calling sys.exit,
with nothing being assigned!!!  Please help.. 

If they would let me rewrite the shell script in python, i would have... but there are a 
few people nervous about having to learn python.


Thanks in advance!
Stuart
