Whilst he has a point, I'm at the moment working in an environment
that works with return values that you have to check at every point.
This is a lot worse - you not only have to check for any return value,
but even if you know that if something is wrong in the subfunction and
you just want your caller to know that (which is fairly common
indirection, and that happens a lot on our systems) you have to
explicitly pass that value up any number of times. Moreso, if you do
not have an exceptional state, you wouldn't get an exception but you
do get a return value that you must check.

Exceptions can be programmed with. Return values cause a lot of code
bloat that doesn't add any values. Solution: /learn/ to program with
exceptions, don't reject them outright.

Oh, and "Considered Harmful considered harmful",
http://meyerweb.com/eric/comment/chech.html .

Back to the original question, thanks for the replies and I'm going to
get a small ARM sometime soon.

Regards & thanks,
Peter
