Hi,
Wellcome on board!

Try using int21:

Eg.:

Code: [Select]


 mov ah,9
 mov dx,text
 int 0x21

text db 'http://www.dbfinteractive.com/',0x24

Hi,
Wellcome on board!

Try using int21:

Eg.:

Code: [Select]


 mov ah,9
 mov dx,text
 int 0x21

text db 'http://www.dbfinteractive.com/',0x24



when i try this in my sourcecode, the program just crashes.
heres my sourcecode:

Code: [Select]

org 0x100
mov ax,13h
int 10h
  mov ah,0Ch
  mov al,0
  mov cx,1
  mov dx,0
int 10h
jmp go
go:
inc dx
inc cx
int 10h
cmp dx,+50
jne go
je go2
go2:
inc al
mov ah,9
mov dx,text
int 21h
jmp go
text db 'http://www.dbfinteractive.com/',0x24

any idea why?

I don't really understand your code, anyway here one example for you to test.
I'm supposing you are using fasm.

Code: [Select]

org 0x100

;----------------VGA mode X - 320x200x256k
mov al,0x13
int 0x10

;----------------write our text
 mov     ah,0x02      ;
 mov     bh,0         ;
 mov     dx,0x0105    ;
 int     0x10         ; cursor position
 mov     ah,9            ;
 mov     dx,text         ;
 int     0x21            ; draw text


;--------------------------------------------------


;----------------Main program loop
Main:

; your code here


;----------------Loop (While not Escape key)
key:
 in   al,0x60
 cbw
 dec  ax
 jnz  Main

;----------------Return to text mode
mov   al,0x03
int   0x10
ret

text db 'http://www.dbfinteractive.com/',0x24
