RE: How to detect a letter?

What about using a regular expression? I know how to use them but I'm
horrible at creating them so if you want to go that route, someone else will
have to generate the expression for you.

Since it's for a password, shouldn't it also include some numerics and maybe
some special characters too?

Hi Michael
This is what I do
D Fromchar c

Const('ABCDEFGHIJKLMNOPQRSTUVWXYZabc-

D defghijklmnopqrstuvwxyz')
D Tochar c Const('
- D
')

C eval Newfield =
C %xlate(Fromchar:Tochar:%trim(Oldfield))

Then see what the contents of Newfield is If its ALL spaces - the
Oldfield contained only upper and lower case a thru z Obviously you
can change the contents of Fromchar to what you need

I'm guessing that someone has already had to do this:
I need to validate that a string contains a letter (A-Z or a-z) as
part of an edit routine for valid email passwords.

I could brute-force this with for-loops scanning for each letter, but
I suspect there is a more elegant solution. Ideas? Preferred solution
would be RPG and/or SQL supported by v7.1.

(Hoped to find a previous discussion of this in the archives, but my
creativity failed me for getting the right search words.) Many thanks.
