Answer 2

In addition to the references dni gave you, the easy rule to remember is that all variables should be local unless you have a specific reason to use a different kind. There's almost never a reason to use public variables; they're a leftover from the early days of FoxPro (actually FoxBase).

I have an application right now which uses these public variables (and calls them lcSomething) all over the place. Such a nightmare...
