Number or Letter

(setq bt (substr text 1 1))        ;CHECKING first letter

I am checking the Fist letter or number of "text"

How can I identify weather variable bt is a number or letter.

(wcmatch) is your friend here

(wcmatch bt "#")

Should return T if bt 'Matches any single numeric digit' . David

Thanks for your help .I can continue now.

You could check without using substr to retrieve the first letter using:

(wcmatch text "#*")

Will return T if the string 'text' begins with a number.
