what's wrong?

What compiler is this? You could be using the wrong assembly notation for your compiler.

I''m just messing around with Dev-C++. I really have no idea if it''s the right notation.

All I can say is that this is completely wrong assembly. You should do:

    asm{        
          mov ax, 0x0005        
          mov bx, ax        
          add ax, 0x0005        
          mov dx, ax    
        }

This is as far as I understand from your code. I hope this gives you some idea.

well, all you can say is wrong, this is not completely wrong assembly. all compilers on earth are not VC++ and do not necessarily use intel''s asm syntax (although I really prefer intel''s syntax), that syntax looks like GNU asm syntax (AT&T?), the one used in GCC.

All I can say is, sBibi, on reading the original post I didn''t kow what the hell I was doing.

Sorry, but that''s just stupid (and I''m being nice). So you''re just guessing the notation and can''t figure why it won''t work. Well, the compiler is not a oracle who can understand every imaginary syntax you input to it. I hope this is a joke.

No, it wasn''t a joke. I was using gnu syntax (and i''m not quite familiar with it, as you can tell) and figured it''d be the same, but wasn''t quite sure.

sBibi, thanks. I replaced ''em with parentheses and it worked.

dev-C++ uses AT&T not INTEL. OH and the command for ASM in DEv-C++ is __asm thats 2 underscores

TAKEN FROM THE DEV-C++ FAQ!1~

How to use assembly with Dev-C++ ?
The "GNU as" assembler uses AT&T syntax (not Intel). Check out this page for more information. 
Here's an example of such a syntax :

// 2 global variables

int AdrIO;
static char ValIO;

void MyFunction(..........)
{
__asm("mov _AdrIO, %dx") ; // loading 16 bits register

__asm("mov _ValIO, %al") ; // loading 8 bits register

/* 
Don't forget the underscore _ before each global variable names !
*/
__asm("mov %ax,%dx") ; // AX --> DX

}

Yes, you're right.
