Ha ha ha ha. Funny! Ok, I'll bite...

Introduction:
This program moves data from one portion of the computer's memory to another, activates some peripheral devices, and attempts to communicate with a human, albeit cryptically.

Algorithm:
For each instruction in the program, execute the instructions in order, except for branches, until the program is complete.

You made my day, thanks! That was fun!

Seriously. We don't do homework problems for you. If you have a question about the assignment, ask it, but don't ask us to fix the entire program for you.

Besides, giving someone a deadline on a free help forum is kind of rude, anyways...

True alc6379, common shabna, we dont get paid for doing this, we are in this to help each other.Chainsaw is a jolly good guy, but if someone wants to take things up a bit, you will find yourself being kicked around.

Btw, check your other post, Stack Overflow has given some very good links which I recommend you read and remmember.
