What are these function used for ?

Hi,
I'm wondering what for are Try, Catch or Throw functions used for. Can someone explain me ?

Many thanks

They are used for error tracking.

If an error occurs within a try - end try block you can catch it with catch o:object; runtimeerror o.tostring() for example.

throw is to throw your own error message for catch

Hmm ok, thanks ^^
