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 itís an alphabetic character. ISALPHA(†) returns false if the character isnít 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.
