It should be the *end* of the try block, or some explicit code as in a
try/catch/end try statement. This makes it much clearer where to put
code to check what failed, eg:

	try
		fail=1
		open(...
		fail=2
		getc(...
		fail=3
		close(...
	catch
		if fail=1 then
		elsif fail=2 then
	end try

Of course if you use three try blocks, you don't need a fail variable.
If you want it to loop, add a loop around the try block(s).

PS The above is structured exception handling, and as I said in my
other post, Rob should get a simpler final exception handler working
first.
