Assembley Lang Findding larges number

Program for finding Largest Number from given Block of data.

Algorithm :-

1. Declare block of five numbers into data segment & largest variable.
2. Initialise data segment.
3. Load counter into CL register.
4. Clear AX register.
5. Load effective address of block into SI register.
6. Move first number into AL register.
7. Increment SI register.
9. Compare first number with second number. If carry flag is set then move second number to AL register, else go to step 10.
10. Increment SI register.
11. Decrement counter.
12. Go to Step 9, if zero flag reset.
13. Store result at largest veriable.
14. Stop.
