I am attempting to read from main memory using masm32 assembly and in order to do this I created (as previously recommended in an answer to another of my questions here) an array that will contain the greatly separated memory locations (in order to avoid reading from cache). I have managed to create the array and have it being read, how...
Hello! I'm trying to query the value located in the Process Enviornment Block, pointed to by the FS segment register. Attempting to compile code with the fs:[0] segment included results in an error (error A2108: use of register assumed to ERROR). How do you query the segment registers?! Thanks ...

Please consider the following data segment. .data res real4 ? x real4 5.0 k real4 3.4 and the following code segments, version 1: .code main: fld x ; 5.0 fadd k1 ; 5.0 + 3.4 fistp res ; store as inte...
When including files into MASM32, it cannot find it's own files. After including masm32rt.inc, the assembler cannot find \masm32\include\windows.inc Apparently most MASM system include files begin with \ instead of specyfing a relative or absolute path. I tried specifying the directory in %PATH%, setting the /I compile switch, and sett...
Hi everyone, So this morning I posted a confused question about assembly and I received some great genuine help, which I really appreciate. And now I'm starting to get into assembly and am beginning to understand how it works. Things I feel I understand alright include the stack, interrupts, binary/hex, and in general what most of the...
Here's the code: .386 ;target for maximum compatibility .model small,stdcall ;model .code main: int 20h END main Result: http://img705.imageshack.us/img705/3738/resultom.png "test.exe has stopped working" - always right when it reaches the interrupt. This is the interrupt I'm trying to use. It should simply exit the ...
How can I detect at compile time from an ASM source file if the target architecture is I386 or AMD64? I am using masm(ml.exe)/masm64(ml64.exe) to assemble file32.asm and file64.asm. It would be nice to create a single file, file.asm, which should include either file32.asm, or file64.asm, depending on the architecture. Ideally, I would l...
I have a simple hello world C program and compile it with /FA. As a consequence, the compiler also generates the corresponding assembly listing. Now I want to use masm/link to assemble an executable from the generated .asm listing. The following command line yields 3 linker errors: \masm32\bin\ml /I"C:\Program Files (x86)\Microsoft Vis...

I just downloaded Embarcadero Delphi 2010 (the trial version). tasm32 and the related stuffs (ilink32, implib, impdef, etc) are still available in it. Still they lack header files and import libs, but fortunately that can be solved by win2inc, implib, etc. The final result can be called TASM32 SDK (in a similar way like MASM32 SDK do). ...

Hey guys, I'm building a Windows Assembly program without any macro. So I downloaded a program that was using macros, and I'm converting this into "pure" assembly code. However I'm facing one issue here. There's a label @@: that I don't understand, and also a jump jne @F that I didn't get it. What are these 2 symbols? MyWndProc: ...

I have a problem because all though I can see the procedures inside the .inc files most of the actual code as been processed into .lib files.
