ISALPHA()


Syntax:     ISALPHA(<expC>)

Purpose:    To determine if the specified character string begins with
            an alphabetic character.

Argument:   <expC> is the character string to examine.

Returns:    A logical value.

            ISALPHA() returns true (.T.) if the first character in
            <expC> is alphabetic.  An alphabetic character consists of
            any upper case or lower case letter from A to Z.  ISALPHA()
            returns a logical false (.F.) if a string begins with a
            number or any other character.

Library:    EXTEND.LIB
