Hi Dear All
Can anyone help me understand the mcode div110(18A5) div120(18AF) div15(18A9). What is this used for?
also what the difference between listing div2-10 vs divide(106F). Understand the div2-10 is for A and C register calculation. So how about the Divide
Thank you!
Regards
Daniel

MCode A B C Register
Hi
When I do A and C multiplication (MP2-10), it return the multiplication to Register C. However I notice it the value in A also some how changed. By right it should remain undisturbed. Why is it like that.
Also, what is the difference between MP2-10 MP1-10 and MP1-13
Regards
Daniel

These are readily available in the .MOD repository in V41 (a great emulator for your PC (if you are using Windows), for example RAM4k.MOD. After loading and activating verify which page it is loaded in and you are ready to r...
