	       On  entry,   GRID  points  to the data structure containing the
	       process grid information.

       MYROW   (local input)	       const int
	       On entry,  MYROW	 specifies the row coordinate of  the  process
	       whose  rank  is to be determined. MYROW must be greater than or
	       equal to zero and less than NPROW.

       MYCOL   (local input)	       const int
	       On entry,  MYCOL	 specifies  the	 column	 coordinate   of   the
	       process	whose  rank is to be determined. MYCOL must be greater
