Hi guys,

I have an assignment and I'm required to create a sudoku using the EMU8086 program. My lecturer gave us a sample. He actually drew borders using the x86 coding. Attached is a picture of the border I'm referring too.



I've never learnt about drawing lines/borders using assembly language. Can someone give me hints?

Thanks!!

if you look at an extended ASCII you will see that there are a bunch of TUI(text user interface) symbols. store these values in in strings as charters and use printf (or what ever function you want to output a string) to output it.

I like this site Extended ASCII Table. Take a look on which you want to use for each. Draw them using a print like the routine I have:

printf:
    mov ah, 0eh
    mov bl, 07h

    .nextchar
       lodsb
       or al, al
       jz .return
       int 10h
       jmp .nextchar

    .return
       ret

After printing the whole sudoku table, make the user input where he wants to place the number and which number he wants. So redraw the table, now using the new number. This would be the easiest way, but uses a lot of memory

If you don't have a user input routine. Here is the one I use:

scanf:       
    mov ah, 00h
    int 16h
    
    mov ah, 0eh   
    int 10h
    
    loop getinput

Also take a look at the emu8086 examples that come within

You're welcome. Don't forget to use the button to regret everyone that helped you to manage it

Nathan , i'm still not very understand about the code , can you explain the code for me ?

It's very simple. It just loops in the characters stored and print them, until it reaches the end of the character sequence

How to store the values ? For the code given by Nathan , is it we need to store in al ? Use DB to define al ? But need to draw the whole table for the sudoku ...

Using stosb you can made it

I'm going to find an example here and I can share it with you, but this will be tomorrow, since it's 1:35 am here in Brazil now and I need to sleep

Multimedia University student also ? XD I've done but the code quite long . I use variable DB for the ASCII codes of the lines and LEA the variable into SI , then lodsb . Then , int 10h to print AL out .
