Returns true if the first character of a string is alphabetic and lowercase.
The string you want to test.
ISLOWER(†) tests the first character of the string and returns true if itís a lowercase alphabetic character. ISLOWER(†) returns false if the character isnít lowercase or if the character expression 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 isLower(†) method behaves identically to the ISLOWER(†) function.
