I am just starting to learn asm. I want to write a small 'Hello World' DOS app. This is what my professor told me should do the job:
I have Visual Studio .NET 2003 and it comes with the newest version of MASM now renamed to ML.exe (it's MASM v7.1).
I tried to assemble my little programm with:
but it gives me the error message:
I also tried the following source which gives me errors too:
I also tried some options like /Zi, /Zm and a different linker but it helps nothing. Please help.
// Edit1: Fixed some wrong code
; hello.asm
.MODEL SMALL
.STACK 256
.DATA
ausgabe DB 'Hallo, Welt',13,10,'$'
.CODE
_start:
mov ax,@data
mov ds,ax
mov dx,OFFSET ausgabe
mov ah,9
int 21h
mov ah,4ch
int 21h
END _start I have Visual Studio .NET 2003 and it comes with the newest version of MASM now renamed to ML.exe (it's MASM v7.1).

you cannot assemble to coff format when doing 16bit stuff, as coff is for 32bit code.
With the later versions of masm, I think /coff is implicit, so you'll probably have to put
/omf on the cmdline to assemble to the shitty old OMF format.
Furthermore, you will need a 16bit linker - try googling this board to find a download
URL, microsoft has it available somewhere on their ftp site.

Thanks for the help f0dder and sorry for posting in the wrong forum.
