  • 1. Since Flash player version 8, the return instruction also makes sure to clear all the data still available on the stack.
Action Flash Version: 

Pop one object and return it to the caller. The result is stacked on the caller's stack, not the stack of the function returning.

Note that up to version 8, your functions could push multiple entries and return all of them to the caller. Since it is not compatible anymore (and it was never supposed to work that way,) it is strongly suggested that you avoid that practice. Instead use a Declare Array action.
