I therefore leap to the conclusion that length(pack("i")) will give me the same as $Config{intsize}.

If that's the case, then I find it a little confusing that 'perldoc -f pack' tells me that the 'int' may be even larger than the 'long', yet %Config is telling me that it's smaller (wrt the particular Linux x86_64 box in question - to which I don't have direct access, btw).

Thanks for alerting me to the alternative.

Cheers,
Rob
