I'm trying to do some basic interrupts in my inline assembly, but when I run the program it performs an illegal operation. The inline assembly works fine when I don't use interrupts.

Here's the code I'm using:

#include <stdlib.h>
int main()
{
asm {
mov dl,30h
mov ah,06
int 21h
}
system("PAUSE");
return 0;
}


It should print '0' to the screen. I've also tried some examples from the Digital Mars FAQs, and the ones without interrupts work fine, but the others crash.

Thanks for help!

Don't think you really can do that in Win32 code...
How did you target the code? DOS 16 bits?

But as for me and my household, we shall use Mozilla...

Yes, I was compiling for Win32...I fiddled with command line args to change it to DOS16 mode and now it works fine. Thanks!
