Programming the 68HC12..HELP!

[relo]

hi and thanks for takin your time to read this..
well basically i need the 68HC12 microprocessor to obey the following guidelines./

Once run the program takes the byte previously stored at memory address 0000h and adds it to the byte at memory location 0001h. It places the resulting byte at memory location 0002h.
Next it multiplies the result by 4, placing the new result at memory location 0003h.
The program now prints the message “Enter Byte” and waits for a key to be pressed.
The byte entered is subtracted from the byte at memory address 0003h and the new result is place at address 0004h.
Finally, this new result is printed to the screen.

any help would be appreciated

This is so obviously a course assignment! - you need to do your own work, not try to get others to do it for you! - this helps no one, least of all you!.

Just checked his IP address - he's even posting from Deakin University in Australia!.
