Hello,

As I know C language is case sensitive, so the problem could be solved
by using UPPERCASE for register names ( for example: ANSEL, PORTB,
TRISB, INTCON ).

Flashing the first six leds LB5, LB4, LB3, LB2, LB1, LB0 with a delay of 1
sec.

I try to flash the leds in the same way : LB0, LB2, LB4, LB6 -- ON and LB1,
LB3, LB5, LB7 -- OFF
and after 1 sec                                  LB0, LB2, LB4, LB6 -- OFF
and LB1, LB3, LB5, LB7 -- ON

#include<system.h>

#pragma DATA _CONFIG, _CP_OFF & _PWRTE_OFF & _WDT_OFF & _HS_OSC & _LVP_OFF

unsigned int counter =3D 0;

void interrupt(void)
{
     if((intcon & 0x05) && (intcon & 0x04))
       {
          clear_bit(intcon, 2);
          counter++;
          if(counter =3D=3D 30)
            {
               counter =3D 0;
               portb =3D ~portb;
            }
       }
}

void main(void)
{
     ansel =3D 0x00;
     trisb =3D 0x00;
     portb =3D 0b10101010;
     tmr0 =3D 0;
     cmcon =3D 0x07;
     option_reg =3D 0b00000111;
     clear_bit(intcon, 3);
     set_bit(intcon, 7);
     set_bit(intcon, 5);
     while(1)
     {

     }
}


When I compile it I receive the next message : error : unknown identifier
'ansel'
                                                                error :
invalid operand 'ansel'
