Matrix dimension error (ERR=124)

  The program does one of the following:

   o  Attempts to assign more than two dimensions to an array
   o  Attempts to reference a one-dimensional array with two subscripts
   o  Attempts to reference a two-dimensional array with one subscript

  Reduce the number of subscripts to one or two or reference  the  array
  using  the correct number of dimensions.  This error cannot be trapped
  with a BASIC error handler.
