Thanks John.  I finally read PEP 394 and 397. Yes, these handle the 
problem on the execute end. The solution to the problem on the 
application development end (my stuff, see previous) is concerning the 
requirement to be able to build apps for both versions in parallel--- 
from the development end.
Ultimately, it would be nice to have support in IDLE for multiple 
versions from under the umbrella of one IDE. I have decided that rather 
than try to port 32 -> 2.7  ( or 27. -> 3.2 ) that I will be developing 
for both (in parallel) concurrently. When I am done with the app two 
versions will be able, one sh-banged for 2.7 and the other sh-banged for 
3.2/
At the moment I am using two instances of IDLE running in parallel, one 
using 2.7.1 and the other using 3.2 /    I would like to see them 
combined under one IDE with configuration options for multiple version 
environments (perhaps in addition to 2.7 , 3.2).
So, I'm playing a bit with IDLE to see what I can come up with. I don't 
know if anyone wants to see a PEP on that or not.
And, while I'm at it, I think I'll look into a way to provide a clear 
screen option for the IDLE interactive window...   :)

kind regards,
