Write a procedure named PackedToAsc that converts a 4-byte packed decimal number

Question

Write a procedure named PackedToAsc that converts a 4-byte packed decimal number to a string of ASCII decimal digits. Pass the packed number to the procedure in EAX, and pass a pointer to a buffer that will hold the ASCII digits. Write a short test program that demonstrates several conversions and displays the converted numbers on the screen. Write a recursive implementation of Euclid's algorithm for finding the greatest common divisor (GCD) of two integers. Note: we will only test this procedure with non-negative integers. Descriptions of this algorithm are available on the web
