A character string.
Returns TRUE if the first character of a string is lowercase.
ISLOWER() returns TRUE if the first character of the Character_String is lowercase; otherwise, it returns .F. (FALSE). This function is normally used to search fields where case-sensitivity has significant meaning. Use this function in conjunction with the SUBSTR()function to test the second and subsequent characters in a field.
