Thanks!  I thought there had to be a way to call the OS' clear screen
command, but was going about it the wrong way.  I was trying to use
sys.clear instead of os.system.  Would it be difficult to test the OS,
store the result in a variable, and call the comand based on the variable
result?  Or would it be simpler to have users edit the script for their OS?

Mind you, there may be other areas where I need an OS-specific command.  I'm
beginning to get an idea of the challenges of portability though. ;)
