   $DESCRIPTION$
      This function converts a value of character, date, numeric, logical,
      array or code block type to any of the other type.  While it is
      guaranteed to return a value of the correct type, that value may not
      be meaningful (i.e., converting from a code block returns an Empty()
      value of the desired type).
   $EXAMPLES$
      nNumericValue := ft_XToY( cInputValue, "N" )
      lLogicalValue := ft_XToY( nInputValue, "L" )
