[Laszlo-dev] try/catch

[Donald Anderson]

I have an implemention of try/catch/finally that matches what the Adobe
compiler produces.  However, I cannot produce any code that fires
an exception and I have not yet implemented 'throw'.  Is there a
way to get an exception - I've tried division by zero, opening  
nonexistent
files, etc.   Throw shouldn't be difficult to implement - is it  
useful to have
try/catch that only responds to throw?
