How to use ports in a loop

If that is what he is asking then, in BoostC, you can do,

Code:

volatile int Ports @PORTA;
int PortBits[16]={
    0x8000,0x4000,0x2000,0x1000,
    0x0800,0x0400,0x0200,0x0100,
    0x0080,0x0040,0x0020,0x0010,
    0x0008,0x0004,0x0002,0x0001
};

void SetPort(char index){
    Ports=PortBits[index];
}

With the above, SetPort(0) will set bit 7 of PortB. Swapping the values in the table will change the order.
