Code can be compiled but it crashes on run

i don't know what assembler you are using - it doesn't seem to be MASM
if you use MASM and a 16-bit linker, this should work

Code Select Expand

        .MODEL  Small
        .STACK  4096
        .DOSSEG
        .386
        OPTION  CaseMap:None

;####################################################################################

        .DATA

s$Msg   db 'Hello World !',0Dh,0Ah,24h

_main   PROC    FAR

        mov     dx,@data
        mov     ds,dx

        mov     dx,offset s$Msg
        mov     ah,9
        int     21h

        mov     ax,4C00h
        int     21h

_main   ENDP

        END     _main

notice that the first instructions set the DS register to the data segment, something your program is missing

You have a problem in the other thread, perhaps you should concentrate on your projects.

Thanks a lot !
The users of this community are very friendly . Tbh when I asked the question I didn't expected a single answer in 12 hours.

What's exactly my problem sir? What are my projects? I don't have any boss here sorry...

cioltealin, if you look for example posted by dedndave you will notice a thing that some persons forgot.
When we declare a string, we use as suffix 0dh,0ah,24h. This means carriage return(0dh), line feed(0ah) and end of string(24h). Windows and linux uses the same EOS (default is 00h) while ms-dos not, it uses a dollar sign ($ == 24h). By default linux use only LF while windows and ms-dos uses CRLF as new line sign.

cioltealin you can try to run your programs with dosbox, maybe will work... :idea:

Don't know if anybody think i was laughing from you, but i was not. I was laughing on the comment from aw27 about your teacher...Just to clarify a little bit and trying to avoid misunderstandings... :redface:
