Notes

Mikero
Note that ArrayName = nil destroys the arrayNAME not the array content. Array content is 'destroyed' when no more ArrayNames refer to the content.
Worldeater
Never ever assign a value to nil! Doing so creates a global variable with the same name that overrides the "command" nil: foo = "foo"; nil = "bar"; foo = nil; hint foo; // displays "bar"
