Turning on LED's one after another, newbie question

Hi

I’m playing around with some LED’s on a 16f630 and I’m just wondering if there is an easier way to do the things I do. It might be a simple question for some, but I never really figured it out yet.

If I want to turn on one LED after another, I normally use something like thins inside a while and with a sleep ofc.

PORTA = 0b000001;
PORTA = 0b000010;
PORTA = 0b000100;

Other times I use RA0 = 1; RA1 = 0; and so on for every LED. It’s working fine and all, but I’m wondering if there are better, more efficient ways to do this?

And what if I want to use both PORT A and C

PORTA = 0b000001;
PORTA = 0b000010;
PORTA = 0b000100;
PORTA = 0;
PORTC = 0b000001;
PORTC = 0b000010;
PORTC = 0b000100;
PORTC = 0b001000; 
PORTC = 0;

Are there any special functions to run through the ports like that?

I have read about bit shifting, but I’m not sure this is what I’m looking for. I have played around with it, but never made it work, so maybe someone could give me an example if it’s actually what I’m looking for.

I use Hitech C and MPLab for my programs.

Thx.

One of many ways…

int i = 0;
for (i =0; i < 8; i++)
{
    PORTA = (1 << i);
    _delay_ms(1000);
}
