I download the last version SimulIDE-R2056_Win32 to test but i found that i can't see my program variable in the variable list

this is my simple code and its compiled and run ok but as i toled befor i can't see my variable var1 and var2 at the list

Code:
//--use-non-free  -mpic14 -p12f675 -V
#define __12F675
#include <pic12F675.h>
typedef unsigned int word;

word __at 0x2007 __CONFIG = _BODEN_OFF &
                      _CPD_OFF &
                      _CP_ON &
                      _MCLRE_OFF &
                      _PWRTE_ON &
                      _WDT_OFF;
char var1;
char var2;

void delay(int mSec)
{
unsigned int i,j;
   for (i = mSec; i>0 ; i--)
      for (j = 110; j>0 ; j--);
}

void main(void)
{
   TRISIO = 0x08;
    ANSEL  = 0X00;
   CMCON = 0x07;          /* disable comparators */
   GPIO = 0X00 ; 
   
    while(1)
         {              /* Loop forever */
       var1++;
       var2 +=2;
      GPIO0 = !GPIO0; 
      delay(500);
      GPIO1 = !GPIO1; 
      delay(500);
      GPIO0 = !GPIO0; 
      delay(250);
      GPIO1 = !GPIO1; 
      delay(250);
         }
}

and this is the debuge window output

That is because the compiler see that those variables are doing nothing in your program, so the compiler "optimizes" it and those variables are removed.

You can try to declare those variables as "volatile", but the compiler might optimize it anyways.
