newbie here,
I just tried playing around with the dec function and
I get errors. Correct me if I am wrong. After getting
the input, the string.split will parse the string
across whitespace chars so in other words you get a
list of each word entered. Then when it does the
eval(x) part it dies. I tries to evaluate the word to
be an existing variable or something. Am I missing
something here.
Thanks
Eric
