   This routine completes inverse by dividing by
determinant.

 ! ª1 1L2 2 Divides element.

   L Decrements index value so it points closer to A.

 !  Loops for next value.

 ! Returns to the calling program or to  ! .
Checksum and length: 1FCF 15

   This routine multiplies a column matrix and a 3 × 3
matrix.


 Sets index value to point, to last element in first row.
