Im having trouble with my assembly language code. Each block should be commented as to what it does, and if it is not obvious, how the code works. That won't input an integer - it inputs a string of characters. Multiply content of AL and CH and store it in AX and then move content of AL into [DI], then increment value of DI by 1. How do you display variables in assembler? Is it possible to create a concave light? To do this there is an argument called what, by which one can specify the data type of the inputted value.

A protected mode example can be found here: I just want to simply get whatever is in the keyboard buffer. Load the value of input in accumulator from memory location 2050 and then copy it to another register say D.Also store 0A in register B. This will improve readability. The .ascii directive only allocates the ASCII characters, but the .asciiz directive allocates the characters terminated by a null. One can use braces for define multiple readline() inside it. This method also uses to reads input from a file also. Any help or advice would be greatly appreciated Then call an interrupt to happen this.Generally call INT 21H for input and output. If you continue to use this site we will assume that you are happy with it. Finally see that while the string which is returned has 6 character, "Chuck\n", the other 80 characters in memory have all be set to zero. This is a better way to comment a program. And because readability is very very important, I've applied the same rule to the labels, mnemonics, and operands.
