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

Subject: How to detect a letter?

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.
