I was just starting to use assembly language (I felt that I had learned something new), and I came across several questions (for now) that all the tutorials that I looked at are not responding or are too old to know.
1) I tried several searches (maybe I just don’t know the right keywords), but I can’t find an updated list of graphic modes for changing the screen resolution, etc. The best I've found is: Assembler Tutorial , and I’m unlikely to think that 640x480 is the best resolution assembly language. Does anyone know of a more updated tutorial that I can use?
Edit: Interrupt 10h is old and does not support more than 640x480
2) Is it possible to "move" a value from a variable to another variable without first transferring it to the register? Example:
jmp start
n1 dw 0
n2 dw 0
res dw 0
start:
mov n1,5
mov n2,6
mov res,n1
add res,n2
...etc...
Edit: This is not possible. You cannot move from memory to memory without using registers.
3) Going with question 1, is there a way to determine which graphic mode the user is using so that I can change it and change it after? (I suppose there is, but I'm not sure how to do this.)
Edit: You need to request an OS for graphical settings.
