If you must have a factorial operator, what's wrong with defining "Fact"?

! meaning 'not' is a prefix operator. ! meaning factorial is a postfix 
operator. So, the two can co-exist.

Actually, I did create a factorial() sub, but that didn't get me out of 
my present predicament. It works as expected when invoked from the 
command line. However, when invoked from a test script (or the REPL) the 
error message is "Undeclared routine".
