! 1L2 Starts root finding routine.
Checksum and length: CE86 010.5

   Evaluates polynomials using Horner's method, and
synthetically reduces the order of the polynomial using
the root.

  

 ! L Uses pointer to polynomial as index.

  Starting value for Horner's method.
Checksum and length: B85F 006.0

   Starts the Horner's method loop.

 !  Saves synthetic division coefficient.

 º % Multiplies current sum by next power of x.

 -1L2 Adds new coefficient.

   L Counts down the loop.

!  Repeats until done.

!
Checksum and length: 139C 010.5
