Starting point for input of coefficients.
)
Loop–control value: loops from I to 12, one at a
time.
! L Stores control value in index variable.
Checksum and length: 9F76 012.5
Starts the input loop.
"!1L2 Prompts for and stores the variable addressed by
i.
L Adds one to i.
! If i is less than 13, goes back to LBL L and gets the
next value.
! Returns to LBL A to review values.
Checksum and length: 8356 007.5
This routine inverts a 3 × 3 matrix.
