Function IsLower() Foundation
Tests whether a character string begins with a lower case letter.
IsLower( <cString> ) --> lLowerCase
If the first character in <cString> is a lower case letter, IsLower() returns .T. (true), otherwise it returns .F. (false).
The character function IsLower() tests whether the first character in a character string is a lower case letter. Lower case letters from "a" to "z" are recognized. If the first character is a digit, blank space, punctuation mark or other graphic character IsLower() returns the value .F. (false).
Language dependent special characters like umlauts or ß, and Š are identified as lower case letters when the appropriate collation table is selected.
The result depends on SET COLLATION and can be manipulated by LocaleConfigure() .
