Need an example of how to use "try" and "catch"

[Tim Jones]

Or - this can be applied to a night out clubbing -

try
    put myBestPickupLine into myMouth
catch theResponse
   If theResponse is not negative
	-- Oh yeah!
	set luckynight to true
   else
	put wittingComback into myMouth
	move body to new location
finally
    if not luckynight then goHomeAlone
end try

Sorry, it's just too obvious…

Tim
