 *  This routine minimizes RAM usage by creating a FLASH resident array to

 *
 *  Creating the array in FLASH is a two pass process.  The first pass puts the
 *  name strings into FLASH.  The second pass actually creates the array.
 *
 *  Both passes use the same pin list.  The list contains two macro names. The
 *  actual macro definitions are changed depending on which pass is being done.
