    Question read console x y position

    i'm searching everywhere to learn how to find the console coord (x, y position) not give it new coord, just find out what the coordinates are for the cursor.

    thanx in advance

    Ive dont this in ASM before, ive posted the code below incase it helps.

    Code:
    mov dx, 0x03D4  ;Get Cursor Position MSB
       mov al, 0x0E
       out dx, al
       mov dx, 0x03D5
       in al, dx
       shl ax, 8       ;Store MSB in ah
       mov dx, 0x03D4  ;Get Cursor Position LSB
       mov al, 0x0F
       out dx, al
       mov dx, 0x03D5
       in al, dx       ;Store LSB in al
    
       mov bh, 80      ;Divide to get XY coordinates (X in ah and Y in al)
       div bh
    	
       xchg ah, al     ;The Y coordinate must be first and the X coordinate last
    The other way of doing it in dos is to use interupt 10, 3 (though i havent used this method before). Heres a discription of how to use it:

    Code:
    Int 10
    
    AH = 0x03
    BH = Video page - probably 0
    
    On return:
    DH = Y co-ord
    DL = X co-ord

    You can use ansi escape codes to save the cursor position.

    Well not really, because the method i used (the first one) actually reads the graphic controllers curser position so will work in any OS (actually i did it in the absence of an OS).

    Oh really? On a SUN system? On an Alpha? On a ...

    Did I miss something..? When did assembler become portable?
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    i've ready the ansi escape codes and i'm pretty sure this is what i need
    ESC[s
    Save Cursor Position: Saves the current cursor position. You can move
    the cursor to the saved cursor position by using the Restore Cursor
    Position sequence.
    but i'm not sure how to use this, any help?

    ps thanx VBprogrammer for the code but i have no idea how to use asm or the code you posted.
