Call a func after a func completes

[Hauken]

Hi.

As the title says, how do I call a function after a function is done with its content.

As of now I have a intro/opening with some pictures e.t.c

After that function is done i want it to call a wakeup script = another function

But its also nice to know because this goes for all scripts, its a good general thing to have in mind but I havent had the need before now to use it.

Im sure some of you know it by head.
