Re: RPG Field Scan

AAARRRGGGHHHH!  Someone actually thinks that code is neat?

Here's two reasons to avoid coding like that:

1) If you ported the code to VisualAge RPG, it wouldn't work since the
PCs don't use the EBCDIC character set.

2) It doesn't work for non-alphabetic characters.  (Granted, there aren't
a lot of useful characters that would be affected.  Two that are of interest
to C programmers, though, are '[' and ']'.  Applying the same technique
to ASCII characters would hit most punctuation, as well as the digits!)

BTW, while we're on the subject, you also should avoid tests like
(CHAR>='A' AND CHAR<='Z') since there are also non-alphabetic
characters within that range in the EBCDIC character set.

Neil,
"Nasty"....is the wrong adjective.  "Really neat" is more appropo!
