Are you asking about the Official Q-code lists as defined by International
Organizations
or
Common usage by Amateur Radio Operators ?

Official Q-codes are at URL:
http://www.kloth.net/radio/qcodes.php

I really haven't seen a reliable list of Ham common usage.
Perhaps the one from an ARRL Operating aid might be sited.
http://home.earthlink.net/~k7bfl/intqsig.html

An example of all this is Official QSX is "Will you listen to ... (call
sign(s)) on ... kHz (or MHz)?"

But Hams on the packet clusters use QSX to indicate where a DX station that
is operating split is listening. e.g., QSX 5 kHz

Official QTH is long/Lat, but Hams use it for city, town, or on repeaters
"Interstate 15 Southbond" or "near the mall" !

Good luck on the project. Going by common usage definitions can be fraught
with errors

The Q code for one's Lat/Long is QTH (is QTF the other set of
Lat/Long?), and for grid square is QRA.

For dx (between QTH and QTF?), there appear to be two possibilities:
QRB and QGE.
Is QRB supposed to be the spherical dx, while QGE is the (ellipsoidal)
geodetic dx?
Or are they pretty much interchangeable?

Likewise, the codes for azimuth (both obverse and reverse) aren't
clear.
QTI is supposed to be the obverse course/track and QTL, the heading:
So which would be considered *the* azimuth/bearing?
The reverse azimuth/bearing unanimously appears to be QTE, right?
