Hi, i have 1 question about inline assembly. as shown in the program listing below, if i remove "asm cli", "i=8, flag=5" statement will not be executed.....why the program doesn't work???  why inline assembly asm makes the difference?   I'm hoping that i can get the answer here. please and thanks.
#include <mc9s12dp256.h>        /* derivative information */
#include "pll.h"                /* defines _BUSCLOCK, sets bus frequency to _BUSCLOCK MHz */

void main(void) {
unsigned int i, flag;
/* set system clock frequency to _BUSCLOCK MHz (24 or 4) */
PLL_Init();
/* set port B as output (LEDs) */
DDRB = 0xff;       // Port B is output
/* allow all interrupts */
asm cli   //weirdness happen here

i = 8;
if (i==8) {

    flag=5;

}

/* forever */
for(;;){}     // remove this to make things even worse...
}

Hi, this is a MAXON Cinema 4D plugin development forum, not a general-purpose C/C++/ASM forum. Unless this problem is related to a Cinema 4D C++ SDK plugin, you would do better on a general computer development/programming forum.

Additionally, you don't give the system (MacOS, Linux, Unix, Windows, DOS), compiler (CodeWarrior, MSC++, Borland, DJGPP etc.), or any other information that would help to narrow the problem. To which compiler is "asm cli" specific, for instance?

Thanks,
