in reply to Simple Regex for Alpha string

/^[A-Z]{2}$/ is about as concise and explicit as you can get for your purposes; probably the only thing that might cause problems are higher order ASCII characters (like accented ones, or Unicode encodings), but for the straight-foward 7-bit character set, you've got it nailed.

It's not what you know, but knowing how to find it if you don't know that's important

    Thanks Masem. I don't expect to encounter HO ASCII but then you never know. How would one handle that situation? If this requires a too lengthy reply feel free to direct me to an appropriate doc or whatever. Maybe Japhy references something like this in his soon-to-be book?

      For handling non-ASCII characters you can do a use locale; (see perllocale) and use the POSIX character class "upper": /^[[:upper:]]{2}$/

        I was going to say the same thing about using a POSIX class, but aside from the perllocale issue. I think generally its better to use them when you can.
