We could probably start a mailing list on the debate regarding the use of globals, but most people are probably tired of rehashing the arguments. There was one passage I read that nailed it down as well as anything: If all (or most all) of your functions use particular piece of data, then that data should probably be global. On the other hand, library functions should never use globals. - Michael Jelinek
