[Tinycc-devel] help with asm function

[Carlos Montiers]

Hello. I want learn assembly, and I playing with 16 bit.

 

I have this little .com file that print the letter Z:

 

 

org 100h
mov al, 'Z'
int 29h
ret

 

But I want use that instruction from a c program with tiny c:

And I have this, but not works:

 

#include <stdlib.h>

int main()
{
 __asm__ (
  "movl $90,%al\n\t"
  "int $0x29"
 );
 
 return 0;
}

 

what is wrong ?
