What is the right way to continue is very application-dependent.
E.g., the OpenOffice spreadsheet does not give up on a division by
zero, but displays "#DIV/0!".

I often use Postscript to generate graphs from measurement data; one
thing where Postscript really sucks at is recovering from errors; if
there is missing measurement data, I have to treat that explicitly in
all the calculations I do (or do the calculations in a different
language) because of that.  If only Postscript had Forth exceptions!
