If/then style question

You have outlined what happens when cond1 and cond2 both evaluate to 
True -- what happens if, say, cond2 evaluates to False?

----- I reply ------------

And the light goes on!  (And palm strikes forehead.)  I was thinking
that the error we were processing was raised by the
do_some_useful_stuff() function.  But the whole purpose of this thread
was to evaluate error conditions that might have been set before we do
useful stuff!  Which, of course, was what the original poster was
asking.  

My thanks again for your patience.
