| Nice to finally know the specifics, but in general this has already been disclosed by both Gygax and Arneson.

It is the spirit of the game, not the letter of the rules, which is important. NEVER hold to the letter written, nor allow some barracks room lawyer to force quotations from the rule book upon you, IF it goes against the obvious intent of the game. As you hew the line with respect to conformity to major systems and uniformity of play in general, also be certain the game is mastered by you and not by your players. Within the broad parameters give in the Advanced Dungeons and Dragons Volumes, YOU are creator and final arbiter. By ordering things as they should be, the game as a WHOLE first, your CAMPAIGN next, and your participants thereafter, you will be playing Advanced Dungeons and Dragons as it was meant to be. May you find as much pleasure in so doing as the rest of us do.
