One thing that no one has addressed so far is why when I put quotes
around my input, as in 'boB', the program does run in the command
prompt.

I am at work now and cannot do these checks. I suspect you are correct
in every particular!

I am beginning to see that instead of "winging it" with installing
BOTH Python 2.7 and Python 3.3, that I should have done some research
first on how to have both Pythons coexist amicably, leaving Python 3.3
as my default for .py files. The reason that I want 2.7 is that at
work after our recent upgrades we have Python 2.4.6 installed on some
machines and 2.4.4 on others. My intention was to try out some Python
2.x stuff at home prior to start using it at work as a replacement for
the scripting I have been to date doing in Perl.

Thanks, Steve (and everyone else!)!
