Is there any way to achieve this without actually making API calls?

If not, may I ask Tomasz to include this in the next release.

so like

Code:

   IF %OS% EQU 5
      display "Windows XP"
   ELSE IF %OS% EQU 6
      display "Vista"
   END IF
... and so on

Thanks.

I'm curious to know the purpose? Is this useful in some places?

Well of course it is. I want to make a program using FASM with some hard coded numbers based on the System's OS version and mode(32bit/64bit ).

From the machine that compiles the source? Which could be entirely different from the machine that runs the code.

I have different OSs. XP, VISTA, Windows 7. The same as having to define a variable or function in C/C++ based on System.

So it seems there's no way. Then we can end this thread.

You can make a file for each target machine OS that you want to compile the code for:

Code:

;MyUberProggyW2K.asm
OS equ W2K
include 'MyUberProggy.inc'

Code:

;MyUberProggyW7.asm
OS equ W7
include 'MyUberProggy.inc'

Then you can compile the code for each target machine on any of your development machines, including Linux, Unix or DOS if you wanted to.

I'll never develop for linux/Unix, dunix or trinix or whatever you call them.

This can help maybe.

Code:

include "%OS%/MyUberProggy.inc"

I am not sure for the value of %OS% environment variable for different versions of Windows.
Although, you should never make OS dependent compilation. It is very, very bad practice IMHO.

For everything since W2K it says this:

Code:

OS=Windows_NT

Although I haven't seen it for W8, it might be different there.
