Hi all,

I am trying to generate dos application in assembly and using masm32. am I on the right path..If i am correct .. masm is assembling my source code.

.model small
option segment:use16

dseg segment para public 'data'

str1 db "Hello world", 0

dseg ends

cseg segment para public 'code'
assume cs:cseg, ds:dseg


mov ax, dseg
mov ds, ax
mov es, ax

cseg ends

end _start

its giving me error on mov ax, dseg.. I don't what to do..

have you tried to do:

MOV AX,SEG dseg ?

I think this should work

not sure what you are after, I just compiled your code

C:\>ml /c /Cp test.asm
Microsoft (R) Macro Assembler Version 6.14.8444

Assembling: test.asm

Try using a 16bit linker :)

Why not to use the simplified segment definitions? :)

.model small
msg db 'Hello world','$'
mov ax,@data
mov ds,ax
lea dx,msg
mov ah,9
int 21h
mov ah,4ch
int 21h
end start

As Azrim noted, the linker that comes with Masm32 is 32 bit and will not create 16-bit DOS programs. To do this, you must have Microsoft's Linker version 5.63 that is available from Microsoft's FTP site: ftp://ftp.microsoft.com/softlib/mslfiles/lnk563.exe.

After extracting the files, I rename the link.exe to link16.exe. You will not be able to use ML.exe to assemble and link 16-bit programs, but you can assemble the program using ML, then link the object file using Link16 like so:

ml /c /Zm /nologo FileName.asm
link16 /nologo FileName.obj;

RadASM can Compiler code 16bit ASM, Please ?

Yes, set-up commandlines in Project Options:

3,O,$B\ML.EXE /AT /c,2


This is for a COM file - linker will produce an error of no output file name given, but it uses a default name that is okay. Seems to work for me.

I have tried the WinAsm IDE for 16 bit code from Insomnia Software. It isn't bad and it is targetted directly at Windows 3.1 applications:


It is also available on the programmers heaven utility disk. It isn't bad for small applications (32K max).
