This is the same dodge that ORD uses, as DocTomoe pointed out: pretending some of the runways are a different heading when they're actually not. I'm not sure how that can be avoided with four runways, though, since I don't see how to fit a fourth option in with "L", "C", and "R". In fact, taking this dodge into account, the DFW example I gave actually has five parallel runways; the two they label 18/36 are actually the same heading as the three they label 17/35. I wonder if they'll ever need to go to six and add an 18/36C.

What's L C R and why can't there be more letters?

  Left, Center, and Right.

  There is also the following suffixes for runway identification: S = STOL runway, G = glider runway, W = water sealane or waterway, and U = ultralight runway. For example runway 8G / 26G in KBDU (Boulder) and 3W / 21W in KSFF (Spokane).

Could just go A B C D E left to right I guess. If only 3 use B C D so the middle is always C regardless of system.

  You want to have a consistent designation for opposite direction runways. (9R is always the same piece of pavement as 27L) Doing that for 4 would need one direction to be A B C D and the other to be B C D E (which is workable, but doesn't seem particularly more elegant than just using left, right, and center [and in fact is worse in some ways, since from one direction, B is the left-most and from the other, it's A])
