The documentation I've found is a little hazy on this subject, so it's time to fire off yet another no-doubt ignorant question:

Is "throw" intended exclusively for the following scenario: Control is transferred out of a try block via a method call, and code in the called method then detects an exception, so the called method uses "throw" to transfer control back to the appropriate catch block associated with the original try block?

A programming langaue will "throw an exception" when some code causes a system/API error ie change in normal program execution flow, which can be for many reason, syntax, logic are main reason, the compiler will throw a error, you can "catch" an exception by identifiy areas in a program that may cause a compile/runtime error and using the PL syntax to deal with this error in an elegant manor.

This is really basic but Exceptions differ between PLs, I guess you are using Java?
