LOWER()
 Convert uppercase characters to lowercase
------------------------------------------------------------------------------
 Syntax

     LOWER(<cString>) --> cLowerString

 Arguments

     <cString> is a character string to be converted to lowercase.

 Returns

     LOWER() returns a copy of <cString> with all alphabetic characters
     converted to lowercase.  All other characters remain the same as in the
     original string.

 Description

     LOWER() is a character function that converts uppercase and mixed case
     strings to lowercase.  It is related to UPPER() which converts lowercase
     and mixed case strings to uppercase.  LOWER() is related to the
     ISLOWER() and ISUPPER() functions which determine whether a string
     begins with a lowercase or uppercase letter.

     LOWER() is generally used to format character strings for display
     purposes.  It can, however, be used to normalize strings for case-
     independent comparison or INDEXing purposes.

 Examples

     .  These examples demonstrate various results of LOWER():

        ? LOWER("STRING")               // Result: string
        ? LOWER("1234 CHARS = ")      // Result: 1234 chars =
