#Emu8086 assembly language code
model small declaring this code will be consists of one data segment and one code segment Then distinguishing label & procedure can be done easily. if multiple label and procedure is present in assembly code. Here at first, indicating start of label and $ indicating start of procedure. PARAMETER : SI = POINTING TO STRING TO FILL.įrom now on you can use number2string and dollars to display numbers. USED BEFORE CONVERT NUMBERS TO STRING, BECAUSE Inc cx INCREASE COUNTER FOR EVERY DIGIT EXTRACTED. Push dx PRESERVE DIGIT EXTRACTED FOR LATER. Mov bx, 10 DIGITS ARE EXTRACTED DIVIDING BY 10.ĭiv bx DX:AX / 10 = AX:QUOTIENT DX:REMAINDER. THEM IN STACK, THEN EXTRACT THEM IN REVERSE org 100h mov ax, 3 mov ah, 0 mov al, 3 int 10h mov cl,10 print: mov ah,02 mov bh,0 mov dh,cl y mov dl,0 x int 10h. I mean to go printing in a different row without changing the column. ALGORITHM : EXTRACT DIGITS ONE BY ONE, STORE There is some way to print a character vertically using a loop for example print the 'l' from (0,0) to (0,10) in in assembly language. Here is your code displaying numbers from 0 to 100 (the comments will help you to understand it). Added proc dollars, to fill numstr with dollar signs (necessary to display, and to clear the string before converting the next number).Collection of beginner friendly emu8086 programs and examples based on Assembly. Tic-Tac-Toe (Jogo da Velha) in 8086 Assembly. Hangman (Jogo da Forca) in 8086 Assembly. Added proc number2string, to convert a number in AX to the string pointed by SI ( this is the most important). Simple Assembly Language Programs (8086) Assembly Codes Emu8086 5.

Added variable lbk (just a line break after each number).Added variable numstr, which is NUM converted into string.Changed the type of NUM, from DB to DW (required by number2string, it would hold bigger numbers).
#Emu8086 assembly language how to
To show you how to do it I made next changes to your code : A few optimizations can be made, for instance: you don't need any fancy dividing, when you can just check if the number given by the user has the last bit set or clear, by using a bitwise AND with a immediate value `0x01` (`0000 0001 b`).The proper and generic solution to your problem is to convert the numbers into strings. It always tries to read at least one number to the "array" (in this case it stores EVEN numbers on a stack, and ignores the rest), but what if user presses '0'?ģ. However, there is no check whether user pressed a number key, or any other key - only `0x30` is subtracted from `AL` after the `INT 0x21` call.Ģ. Since the assembly language is very close to the machine language, its possible to control computer behavior in a very specific manner. But its a weird language and its not simply binary code with 0s and 1s. It expects only one ASCII character, so technically user can input only numbers from '0' (ASCII `0x30`) to '9' (ASCII `0x39`). Its so close to the machine that its hard to call it a language. MOV AH, AL ADD AH, AL PUSH AX INC CH JMP RETURN NOEVEN DB 0AH, 0DH, "NO EVEN NUMBERS IN ARRAY!!$" MSG DB 0AH, 0DH, "ENTER A LENGHT OF ARRAY: $"ĪRRAY DB 0AH, 0DH, "ENTER ELEMENTS OF ARRAY$"ĮVEN DB 0AH, 0DH, "TOTAL EVEN NUMBERS ARE $"ĬONTINUE DB 0AH, 0DH, "CONTINUE? $" MSG1 DB 0AH, 0DH, "THIS PROGRAM ACCEPTS SIZE OF ARRAY AND ELEMENTS THEN PRINTS EVEN NUMBERS$" This program is written using 8086 assembly language using emu8086 software.

This program takes user input as an array and then determines the number of even numbers and prints them.
