what is the output, what does "enum" do?

It specifies a 'group' of constants. For example, if you have a function called CreateAlien(type), there are only going to be a set number of possible inputs that you support. A neat way of encapsulating that (and validating the inputs) is to use enums.

For example:

Enum AlienTypes
Alien=1
Predator=2
End Enum

Function CreateAlien(type:AlienTypes)
...
End function

CreateAlien(Alien) ' works
CreateAlien(3) ' doesn't work

Having said that, they're not something I miss enormously, although they are seriously handy if your IDE has intellisense, as you would see a dropdown of the valid enums to select from...
