Question: (30 points) Write a Pep/9 subroutine MULBY2 that takes a single parameter a pointer to an array of 30 bytes. Each byte in the array

(30 points) Write a Pep/9 subroutine MULBY2 that takes a single parameter a pointer to an array of 30 bytes.

Each byte in the array is an integer in the range 0..9 thus the array represents a 30digit decimal number. The subroutine should modify the array contents so that the number represented doubles. You may assume that the new number will fit in the array: there will be no overflow.
