It gets all the information from the stack. It knows where to search for characters because it knows who called it. If you run it to fast you may not see anything.Ī far procedure that prints out "hello" using a very tricky way. (since we get result in AL, you should useĬall a procedure from another segment or interrupt.Ī more detailed example, it's interesting to see what happens with the stack when it runs slowly. Use PRINT_NUM procedure from "emu8086.inc",

only lower case letters are encoded (but this program can be improved to convert full abc if required).Īnother "Hello, World!" example - exetest.asmĬalculation and vice-versa. The second table does the reverse, it sets letter Tables are precoded manually to decode one another.įor example if first table sets letter 'a' to be 'k',

This code prints out current date and time and saves it to a file.Įmulator saves this file to emulated file system.Ĭase alphabets of a string using XLAT and also decrypt the same.

This examples shows how to modify Interrupt Vector and create your own custom interrupts. Make your own interrupts - Custom_Interrupt.asm Ĭount number of key presses - Count_Key_Presses.asmĬounts number of key presses, and stores the result is in BX register. That means by using the loop and READING ONE CHARACTER in each time of loop. This source code shows how we can count the number of letters in some statment without using string instructions, This is a program in 8086 assembly language thatĪccepts a character string from keyboard input (Max of 4 ASCII digit) to equivalent packed BCD digits. That can be used for converting a string of number This program uses a subroutine written in 8086 assembly language Based on original (much more complicated) input routine taken from emu8086.inc This code supports both positive and negative numbers as input. When I run this program on emu8086 it proves that ' -1234' is actually 0FB2Eh in hexadecimal (or binary: 1111101100101110b). This program written in 8086 Assembly Language to convert string value to binary form.
Learn how to set and get file attributes, in other words how to make file Read Only or Hidden.īCD - AAA instruction example - bcd_aaa.asmīCD - AAS instruction example - bcd_aas.asmĬommand prompt based simple calculator (+,-,*,/) for 8086. It's required to set correct data type (size) and number of elements in that array: Not only variables but arrays can be seen in memory. (set Elements for SEG1, SEG2 and SEG3 to 4 and In emu8086 you can see the result in " View" -> " Variables" menu. This example calculates the sum of one array with another and saves result in third array.
See how to operate with Octal, Binary and Decimal values. "HELLO WORLD!" by writing directly to the Your own Operating System that runs from floppy drive - easy!Īnd this program draws a tiny geometrical figure in VGA mode. Input 8 bit binary number and print out its decimal equivalent.
