Reset?

My two cents:
resetting variables is dangerous: there can be too many of them, and it is easy in a future develeopment to add another one and just forget to clear it.
The best way is to incapsulate logic and variables in one (or more) class module (this is what classes are for). Destroying and creating a new class will reset everything (including allocated memory) and gives you "fresh ground" to start with.
If the "damage" is already done and all your code is in a form, just unload that form and create a new one (not elegant, but safer than trying to reset everything). If the code is in a bas module, just move it into a class.
