I'd better buy your book when it comes out :-) Until then, HEAP_GC and its
friends RETALL, WIDGET_CONTROL,/RESET and CLOSE,/ALL are mighty handy from
the command line when cleaning up after an error.

This has been discussed on the group before, but I'm not keen on excessively
enthusiastic error handling in code. If in doubt, stop where the error
occurred and let the user sort it out!
