ERROR - The program either:

   o  Contains  a  MAT  IDN,  MAT  TRN,  or  MAT  INV  performed  on   a
      one-dimensional array
   o  Performs a matrix operation that requires identical bounds in  the
      operand arrays and those arrays have different bounds

  Dimension the arrays to the proper bounds.

  ERROR - You specified the wrong dimensions in  a  matrix  in  the  MAT
  multiply  statement  or  a  WITH  clause  on  the  DRAW  statement.  A
  2-dimensional matrix with lower bounds 0 and upper bounds  4  in  both
  dimensions  is  required.   Declare  the  matrix to be a 2-dimensional
  matrix with lower bounds 0 and upper bounds 4 in both dimensions.
