It does include P-line in that table, but I think it's a lazy copying of the K-5 manual without editing. I've searched the K-30 manual and it makes no reference to Program Line exept for its appearance in that table on p162. The first post in this thread asked what P-line meant for the K-30, presumably because the OP couldn't find it either.

I assume it has a P-line, but its fixed. So - pushing the green button uses this (fixed) P-line. The name P-line is quite weird BTW.

IMO the "Program Line" name is logic, at least when you know where it comes from.

"Program Line" is the line you get when you plot the program on a shutter speed/aperture diagram. This diagram used to be included in most SLR manuals, but I have never seen it in DSLR manuals.

"Normal" Program Line in Pentax Z1 using a 50/1.4 lens with ISO100.
