      [<cString>]       is the string for whom the function generates a list
                        of all characters
                        Default: "" (empty string)
   $RETURNS$
      <cCharacterList>  a list of the characters in <cString>
   $DESCRIPTION$
      The CharList() function generates a list of those characters that
      are contained in <cString>. This list can contain each character
      only once, so that its maximum length is 256. The list lists those
      characters first that are occuring in <cString> first.

      ? CharList( "Hello World !" ) // --> "Helo Wrd!"
