Microprocessor(Program to find out largest number)

A program to find out the largest number from a given unordered array of 8-bit numbers,stored in the location starting from a known address.

Logic:    Compare the i th number of the series with the (i+1)th number using CMP instruction .it will set the flags appropriately depending upon whether the i th number or the (i+1)th number is greater.if the i th number is greater than (i+1)th number is greater than (i+1)th, leave it in the AX(any register may be used).Otherwise load the (i+1)th number in AX,replacing the i th number in AX.The procedure is repeated till all the members in the array have been compared.
