1.The code always get RUN-TIME error with DEV-C++ ! But it runs correct if it
is compiled with DJ Delerie's DJGPP
2. The assembly assembled with NASM.
3. I am sure the "call _rand" cause the run-time error but don't know how to fix.
4. its a win32 console application, compiled with dev-c++ correctly.

C code

include <stdio.h>

include <stdlib.h>

int asm_fnctn(); / protype the external ASM fnc /
int main()
{
int rnd;
rnd=asm_fnctn();
printf("Random num. = %x\n",rnd);
return 0;
}
