hello
how can i appear a scrolling text on the screen :( i want a simple program please
Part 1: draw text on screen.
Part 2: Draw text on screen at previous offset - 1
Part 3: loop at part 2
Or use Interrupt 10h functions 6 or 7 to scroll the text, and then update the top or bottom line.

1. Learn how to display text on the screen
2. Learn how to place text at any position on the screen
3. Put the two together :wink
hello tedd i do my homework :bg
i did what do you want me to do :wink
and now how can i scroll it :toothy
declaration segment
assume cs:declaration
CALL start
start proc
mov ah,06h
mov al,00h
mov bh,07h
mov ch,00h
mov cl,00h
mov dh,24
mov dl,79
int 10h
mov bh,0
mov dh,12
mov dl,35
mov ah,02h
int 10h
mov dl,'A'
mov ah,02h
int 21h
mov ah,4ch
int 21h
start endp
declaration ends
end start
If by scrolling you mean that the screen should simply scroll up after the CRLF on the last line, any BIOS function that updates the cursor position and processes CR (character code 13) and LF (character code 10), or any DOS function that calls one of these BIOS functions, will do this.
.model small
.stack
.data
string db "xxx",13,10,"$"
.code
.startup
; Loop through 40 lines.
mov cx, 40
@@:
; Display the string. The terminating CRLF will cause
; the function to move the cursor to the start of the
; next line, and when the cursor reaches the bottom
; of the screen, scroll the screen up by one line.
mov dx, OFFSET string
mov ah, 9
int 21h
; Wait for a key press before continuing.
xor ah, ah
int 16h
dec cx
jnz @B
.exit
end
thank you for your help
i think there are some mistakes in your code it doesn't work :(
The code assembles, links, and runs correctly on my system. I have now added some comments that explain what the code is doing. What problem are you having?
hello MichaelW
look there are two fault in line 6'.startup'
and in line 25 '.exit'

I had no idea you were using MASM 5.1. Here is a version that should work with 5.1:
.model small
.stack
.data
string db "xxx",13,10,"$"
.code
start:
; Set DS to our data segment.
;
mov ax, @data
mov ds, ax
; Loop through 40 lines.
;
mov cx, 40
@@:
; Display the string. The terminating CRLF will cause
; the function to move the cursor to the start of the
; next line, and when the cursor reaches the bottom
; of the screen, scroll the screen up by one line.
;
mov dx, OFFSET string
mov ah, 9
int 21h
; Wait for key press before continuing.
;
xor ah, ah
int 16h
dec cx
jnz @B
mov ah,4ch
int 21h
end start
thank you MichaelW
