Global Variables: How many is good?

[storydragon]

I often stress a bit when I’m managing my global/local variables, and I’ve had this question:
What’s the appropriate number of global variables to declare when programming to avoid namespace pollution?

This StackOverflow thread is pretty interesting. Essentially, it says you should have as many as you need, without anything unnecessary; if you can have something locally scoped, do, but don’t worry about having global variables, as long as they’re necessary.

This helps a lot! Thanks!
