    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,
