  1. First number is greater than second number

  2. First number is less than second number

  1. (a) Write a program to find the largest number in a given data array

  1. Write a program to move a block of data from one section of memory to another section of memory.

  1. Introduction  for Microprocessor 8086

  2. To add two eight byte number stored at location 0000:1300 to 0000:1307 with the number stored at location 0000:1308 to 0000:130F,the result is stored from location 0000:1308 onwords.

  3. To find the maximum number in a given string (16 bytes long) frommemory location 0000:1300 to 0000:130F and store the result in location 0000:1310
