How to Read a Character From a Keyboard in Assembly
Writing code in assembly language allows you faster access to a machine's hardware. If you have an assembly program that requires a user to input a character from the keyboard, your program needs to read the character to know what to do next. For example, if you need the user to enter a "Y" or "N," you need to tell the computer to read the entered character.
