<p>Thanks. That clears it up nicely. I read the bit about not using printf when print will do, but I did not know to look for ord.
I was hoping that by specifying $ca with single quotes, instead of double quotes Perl would not treat $ca as a string.
As the other reply hinted, I have been doing C recently, and Perl is not C.
Thanks again.
