Sorry for replying to myself, but after reading the reply message I
posted to you last night, perhaps a bit more explanation is in
order...
First, here's what I wrote last night:

>> 36L (opposite direction of 18R)
>> 18R (opposite direction of 36L)
>> 18L (opposite direction of 36R)
>> As you look down the runway (for either take off or landing), the

To continue...
Keeping the two parallel north/south runways example I cited above,
here's an example of what you might encounter from ATC (badly
paraphrased, I'm sure):
Let's say that you're approaching an airport from the north (flying a
direct south heading of 180), and ATC tells you to land "straight in,
using runway 18L".
Since you're already flying a heading of 180, you're already flying
in the direction that you'll be landing on "runway 18L" (hence the
"straight in" instruction). In order to line up with the proper
runway, you'll be wanting to line up with the runway to the left (the
"left side" one of the two parallel runways as you see them during
approach).
If, on the other hand, while you're still approaching the airport
from the north (heading 180), ATC instructs you to land on "runway
36R" (this will be the very same strip of tarmac as "runway 18L", but
approaching from the opposite direction), you'll have to fly the
pattern past the runway, then, once beyond the runway, turn 180
degrees so that you're now flying at a direct north heading (360).
Now you're ready to approach and land on "runway 36R" (as you're
approaching from the south, it will be, of the two runways, the one
on the right).
For simplicity, I've only used an example of a perfectly north/south
oriented runway. Runways, of course, can be pointed in any direction,
so the name of a runway will always tell you just which heading you
need to be flying in order to land on that particular runway.
Naturally, finding the correct runway for take off follows the very
same runway naming system, so if you're told to taxi to "runway 36R",
you'll taxi to the south end of "36R", line up on the runway with a
heading of "360", and take off flying north.
