Functions and arrays (ruby)

[meghatronic]

Is it possible to access a function defined/filled array from outside the function?

e.g.

def foo()
 arr = [blah blah blah]
end

foo()

puts arr

I'm not really au fait with ruby, but to do this in another language you would normally have to make the arr variable global or return it as a public variable inside the function.

I've read that to do the former was bad so was looking for an alternative....

Referring it as a public inside isn't really an option so I've settled for a global var for now before I rewrite the blasted thing.

The problem is my function does a few things so I can't call it as above.

I'll just have to use global arrays ... or rewrite.
