How do I check if an integer is uninitializer

[The Undaddy]

or is equal to -1?Main problem is the first part.

And no, I have not tried doing it myself, I'm off to school in 15 minutes

Edit: uninitializeD

When you see you haven't set a value?

local integer i
integer i

Yeah well...
My question is more kind of checking it in-game.
You know when warcraft is running

there is no "correct" way for checking that, but you can simply
set i=i+1 (or any function call with an uninitialized variable, like SetUnitX(u,0.) )
will cause the thread to break. So if the code after that line isn't executed the variable is unitialized. (and for example a global boolean not set to true to check it from another function)

But this is really... not a nice way of doing it. initialize with "null" or 0 and use normal if then elses ;P
