RE: isalpha

[Joel Fritz <JFritz@xxxxxxxxxxxxxxxx>]

Soo... Barbara's post came up first.  I made a little mistake that makes the

that a C character is an integer type.  I guarantee unexpected results from
the code below.  I've tested it.  It runs.  It gives results.  You may or
may not like them.
