ISLOWER()
Determine if the leftmost character is a lowercase letter
------------------------------------------------------------------------------
Syntax
ISLOWER(<cString>) --> lBoolean
Arguments
<cString> is the character string to be examined.
Returns
ISLOWER() returns true (.T.) if the first character of the character
string is a lowercase letter; otherwise, it returns false (.F.).
Description
ISLOWER() is a character function that determines whether the first
character of a character string is lowercase. It is the inverse of
ISUPPER() which determines whether a character begins with an uppercase
character.
Both ISLOWER() and ISUPPER() relate to the LOWER() and UPPER() functions
which actually convert lowercase characters to uppercase, and vice
versa.
Examples
. These examples demonstrate various results of ISLOWER():
? ISLOWER("aBcDe") // Result: .T.
? ISLOWER("AbcDe") // Result: .F.
? ISLOWER("1abcd") // Result: .F.
? ISLOWER("abcd") // Result: .T.
