Title: Printing Integers in nasm
Post by: computertrick on February 17, 2010, 04:33:59 PM

Ok well i am planing to make my own calculator using nasm

it is going to be made completley from scratch even the machine

and unfortunatly i have no clue how to recive integers in nasm

for example in windows console applications when you type things it shows it in the console window

how can i do this in nasm for dos since i want to also make the operating system  ???
