I don't understand Program-mode..
It's not hard to understand. The camera picks shutter and aperture..
You have other modes like Tv, Sv or Av then why use P-mode? What doesP-mode achieve that the other modes can't do?.
When you don't really care what the shutter or aperture are, and you want the camera pick some reasonable value so you can get the shot. Some examples:.
You are in aperture priority and set to f/2. You are shooting in changing lighting conditions (inside to outside, shade to sunlight, etc). In brighter light you might not have a fast enough shutter speed to compensate. Similarly with a small aperture moving from bright to dim lighting. And again similarly if you are in shutter priority and the shutter speed is too slow/fast to have aperture alone adjust for different lighting..
Or you'd like to have the shutter speed be fast enough to minimize camera shake. A bit of a pain with zoom lenses in shutter priority unless you want a fast shutter all the time. A major pain in aperture priority. P on most (all?) cameras does this..
Or you are shooting with flash in changing lighting. At least on Canon DSLRs the flash automatically changes from main to fill lighting depending on the exposure value of the scene..
Or you want to pull out your camera and shoot, without worrying if you've got things setup or not. I'll do this if I see something but don't have my camera ready, especially something that isn't going to be around long. Turning the dial to P is quicker than figuring out if I've got the right setup in another mode..

Program mode is the same as Auto mode except that Program Mode gives you the ability to control a few more functions such as white balance and exposure compensation. Your camera manual probably has a chart that lists all the functions available in each mode. Compare Program to Auto to see what functions are available for your camera...

Program mode implementation varies between manufacturers and cameras. Therefore you should have asked this question in Pentax DSLR forum because now you get somewhat misleading answers .
P mode on your K10D (Pentax calls in Hyper Program) automatically sets aperture and shutter speed according to Program Line however it allows you to switch instantly to shutter priority mode by turning front e-dial or to Aperture priority mode by turning rear e-dial. Presing green button sets camera back into automatic mode..
