Would anyone know how to get command-line arguments in NASM16? I am on a Windows XP. I have tried a great deal of things and spent much time searching for an answer to this.

What I ment by command line arguments, something simple like this would be enough.

Filename: Hello1
Params: one two three

So when you type "hello1 one two three", it would see that you typed "one two three", and say something along the lines of

Param 1: One
Param 2: Two
Param 3: Three

I am really against using C libraries (I prefer to do everything purely in assembly).. So if it is possible to do it without C, I would really appreciate your time to answer.

Someone may ask "Why would you want to do this? Just use a higher level language.".. My short answer would be that I enjoy using assembly over a high level language, because of its complexity.

Not sure what NASM16 is? Is this 16 bit programming?

I would assume so. It came with the book "Assembly language step-by-step". I have had it for a while and it works fine. (After looking around, MASM32 is 32 bit, so I think Nasm16 would be 16 bit).

And not sure if this means it's 16 bit, but I normally put [bits 16] at the top of my code.

Is it possible to get a command-line argument with C? I do not like the use C libraries because to me it does not feel like real assembly. To me, real assembly is 100% machine instructions.

I know how to do it in 64 bit assembly using Linux's as. You just take the offset of the rsp register.i.e

16(%rsp) will get the first command-line argument

In 32 bit Linux's as

8(%esp) to get the first command-line argument

...For 16 bit...I don't think Linux supports 16 bit exe's so I never had the opportunity to try but if it did it would probably be an offset of the ss:sp registers...Hope this helps

Thanks. I would not know how to test this on windows as I have never used Linux, but I appreciate your time to reply.

Windows will pass the command line arguments via the stack so you'll get then by taking an offset of the stack pointer. In 16 bit programming I believe that is accomplished with ss:sp

where ss is the segment register and sp is the stack pointer together they will give you the base of the stack

How would I go about doing that? The most i've ever done with assembly was a "Press any key to view its hexidecimal\binary value". I think I may have heard of ss:sp before, but I have no clue how to do anything with them. I understand if you don't have the time to make a code to show me.

Try this link. It discusses 16 bit programming with nasm

http://developer.apple.com/mac/libra.../nasmdoc7.html

That did help a bit. But I still cannot get it to work.. I did, however, make a code as proof that I tried. It is supposed to check if the first argument is the "a" key, then display "It works" if it works.
Here is the code.

Did you try Googling "Windows XP 16 bit programs"
