Hey,

I've been searching around in the DOS stuff on this forum, and I've learned some basics of DOS now.

Now I searched for this too, but I didn't really find it, my question is:

How can I output a string with a specified color in DOS? (or with BIOS int)
Just like this:

Code:

mov ah,9 ;int service 9
mov dx,text ;offset to text
int 21h

;but then with colored string output?

Thnx

These simple routines are from the "kelvar" example (you can find it in the "Examples" section of this website):

Code:

display_character:
; al = character
; bl = color
        xor     bh,bh
        mov     cx,1
        mov     ah,9
        int     10h
        mov     ah,0Eh
        int     10h
        ret
display_text:
; ds:si - text
; bl = color
        xor     bh,bh
        mov     cx,1
      .display:
        lodsb
        or      al,al
        jz      .end
        cmp     al,0Dh
        je      .type
        cmp     al,0Ah
        je      .type
        mov     ah,9
        int     10h
      .type:
        mov     ah,0Eh
        int     10h
        jmp     .display
      .end:
        ret

Yes I've looked at the kelvar with a bootup floppy, very nice engine you wrote Tomasz Smile

Thanks for the little code snippet, I'm going to experiment. (I'm new to DOS, before I only programmed in Win32) Smile

I've sorted the INT 10h out now with the Ralph Brown Interrupt list, now I completely understand the routine Smile

Thanks again Tomasz Very Happy
