Assembly Program to find Smallest Number in an Array

This program has a byte ARRAY and a variable called the SMALLEST. The program will find the smallest integer in the ARRAY and will assign it to the variable SMALLEST.

The basic logic in the program is that we assign the first element of the array to the SMALLEST and start iteration from element 2. If the element 2 is smaller than the value assigned to SMALLEST, we update SMALLEST otherwise go to element 3 and compare SMALLEST with element 3 and so on.
