Thanks, that's exactly what I wanted to know - the existance of the 
globals() fuction. This should solve some problems for me. As you can 
probably tell, I haven't been using Python for very long.

(Also, I recently discovered I can use nested functions PHP style - is this 
a new feature?)

Thanks again,
