 Reverse the color of a single character on the screen
------------------------------------------------------------------------------

 Syntax

      FT_REVCHR( <nTRow>, <nLCol> ) -> NIL

     This is a high speed function to reverse the color of a single

     FT_REVCHR( 10, 20 )

     This example will change the text and background at 10, 20 to it's
     reverse color attributes without changing or overwriting the
     character itself.
