Need help in Assembly language coding?

Question

I am new to Assembly Language. I am coding in 16-bit addressing mode using Irvine16.inc. How do I add 2 16-bit integers and then store the sum in a 32-bit integer? Also, how do I subtract a 32-bit integer from a 16-bit integer?

I am also getting a A2008 error from Command Prompt. How do I read these errors? Is there a website where the error messages are explained?

Answer 1

you can start by saving one number in a register, then use ADD command, to add from that register, with the other number, and it will save the result in the sumation register.

You need to get documentation for ur Processor, there is no way around that.

Good Luck
