ISALPHA( )
Returns true if the first character of a string is alphabetic.
Syntax
ISALPHA(<expC>)
<expC>
The string you want to test.
Description
ISALPHA( ) tests the first character of the string and returns true if it’s an alphabetic character. ISALPHA( ) returns false if the character isn’t alphabetic or if that character position is empty.
The current language driver defines the character values that are lowercase and uppercase alphabetic. In a U.S. language driver, a lowercase alphabetic character is from a to z, and an uppercase alphabetic character is from A to Z.
Other than the syntactic difference of being a method instead of a function, the isAlpha( ) method behaves identically to the ISAPLHA( ) function.
