------------------------------------------------------------------------------
 Syntax

     LOWER(<cString>) --> cLowerString

 Arguments

     <cString> is a character string to convert 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 upper and mixedcase
     strings to lowercase.  It is related to UPPER() which converts lower and
     mixedcase strings to uppercase.  LOWER() is related to the ISLOWER() and
     ISUPPER() functions which determine whether a string begins with a lower
     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 =
