How to get user input in assembly language? Would int 0x16 wait until a key is pressed? they can input 1, 12, 123, 1234) I know how to ask the user for whatever number they want, using a loop and then using the mov ah, 1h function, but I want to take the user's input, let's say 123, and then store that number in a variable that I've created, Y. We already know the answer. For the code that I have now if I enter 123 as the user input it gives me that the Sum is : 0098, and W is 1, which shouldn't be the case, the Sum should actually be 0189, and the W is 6.

LOAD X: Loads the value stored in X to the AC. Store 00 in CH register. In this lesson we use software interrupts to request system functions from the kernel in order to print out 'Hello World!' to the console. So the best way to use that inputted data as character is to convert the data to a character. If you want to program the BIOS, check the RBIL.
