Assembly langauge 10h and 33h arent working

I'm using the flat assembler writer with windows xp and I have these two functions that don't seem to position the cursor but wikipedia and a book I'm reading says they position the cursor. I was hoping someone could tell me why and maybe show me an example of a low level program that will position the cursor.

INT 10h/AH=02h works for me. Can you show a short program of how you're using it & explain what you expect to happen and how the program's actual behavior differs?

INT 33h calls deal with the mouse. I don't know how well they'll operate on a modern system.

both of those are how I run the program with the flat assembler for windows. each are different programs and neither make exe files. They make .bin files when I compile them. I'll post the exact code for int 10h again it's exactly what I posted. Also I am a newb at assembly.

The code snippet you posted is perfectly fine by itself, so the problem must be in the code that uses it, or in your expectations of what happens. So for me to understand your program I need to see complete code and know how your expectations differ from what the code actually does.

This website has tips for creating such an example. For example, here's a short program that writes text around the middle of the screen.



If you're not producing executables, how are you running the programs? I have not used the Flat Assembler program you mention, but from its manual it looks like you would use it to create object modules & link them into an executable like any other assembler. If you're using some type of interpreter or emulator to execute your code you need to make sure it supports the BIOS/DOS interrupts you're using.

You need to be creating a segmented 16-bit DOS program, not a flat 32-bit windows program.

You need to make it a 16-bit executable so that windows knows to load DOS-VM to run your program in - where 16-bit interrupts like int10 actually mean something.

Alright the code I posted was exactly what I used and it doesn't work on the flat assembler. Your code doesn't work when I use it because of the .data string the main proc string the main endp string the .code string and the one that really sticks out to me is the lea string doesn't even compile.

I wanna ask Salem how to make a .bin file into an executable with fasm but I'm gonna do some research for that. That might be the reason 33h isn't working. Heh when I compile the program I get a bin file. Duh that's not executable. I guess My question is if anyone knows how to make exe files out of bin files.

According to the download page you need to download the DOS version of the program to generate DOS compatible executables.

They also have a message board which would have been a good place to ask, if you haven't done so already.

No, this is not true. All versions of FASM has the same features. They only run on different operating systems. The above code snippets are simply not in FASM syntax.
The proper code is:




The flat assembler forum is really great place to ask questions about assembly programming for Windows, Linux and any other OS.
