How to check a password is only alpha characters?

[Michael Kear]

Uh oh. I just bit off more than I can chew here I think.

I'm checking a submitted password for validity before updating my user
database. One of the requirements is that the password be made up of only
the characters a-z, A-Z and 0-9.  In other words, no punctuation, dashes,
underscores, spaces etc.

Can someone please tell me what code to use to test variable newpassword1
for this?

Thanks,
