all of the following will do a bsf PORTA.2 in MPC

#pragma portrw PORTA @ 1;
PORTA.2 = 1;                // This will set bit 2

PORTA = PORTA | 4;     // This will set bit 2



struct {
             int bit0 : 1;
             int bit1 : 1;
             int bit2 : 1;
             int bit3 : 1;
             int bit4 : 1;
             int bit5 : 1;
             int bit6 : 1;
             int bit7 : 1;
        } porta @ &PORTA;

porta.bit2 = 1;               // This will set bit 2


bit  porta2 = &PORTA,2;
porta2 = 1;                   // This will set bit 2
