checking your LIST I think your only problem is the "#" character... maybe the editor you have used is UNICODE or sort of that, maybe your OS... also... the numbers are beginning with 0 and not with o??? ( 0FFh could be write OFFh)

have you checked this???

Your assembler does not like the # character, Perhaps try a different assembler.

I use the assembler ASM51 on the Window XP OS, and the code is written by using Notepad. Can you propose any other assemblers?

By the way, many thanks for your help.

Why don't you try keils A51 assembler!
Download the entire IDE, I think. It will help you.

Thanks for all of your help.
Please post your fixed code or send it my email address lengoanhcat@gmail.com, IanP.
Can you give me you personal information, IanP? I use it for my acknowledgement of my report?

Attached are your original KEYPAD file and its HEX version ..

If i compile your code the error is this:

you write

IN_HEX: MOV R3, #50D;debounce count

BACK2: MOV R3, #50D;wait for key up

maybe you should write #50H

I use pinnacle or keil for my assembler
