do try/catches cascade?

Not sure if that's the proper term.

Let's say I have this:

function function1()
try
do something
function2()
catch
error
end try
end function
function function2()
try
do something
catch
error
end try
end function

When function 1 is called, will it abort if function 2 also aborts? Or will
function 1 do whatever it can regardless of whether function 2 aborts or
not?

What did you observe when you tried it for yourself...?

Good question darrel.

Exceptions "bubble up," which means that when an exception occurs, and is
not handled, it is passed to the calling function. So, if the calling
function doesn't handle it, it throws the same exception, which is then
passed to the function that called IT. And so on. So, whether the exception
bubbles up is determined by whether or not the exception is caught and
handled gracefully in the function in which it is thrown.

Thanks, Kevin. That explains it nicely.
