Perhaps your memory is different to mine, but I remember all
sorts of frustrating, nasty, undocumented problems with apps
that just grabbed an "interrupt ... and did what they wanted".
It was a support and maintenance jungle - but possibly you
remember it differently to me.

Yeah. With the emphasis on 'cooperative'. Anything that
broke the rules even slightly brought the whole house of
cards down on it's arse. Or is this my memory failing me
I'm not going to pretend that Palm OS was brilliantly designed,
but I think your repeated howls to return to the "good old
days of DOS" aren't taking into account that most of what
you're working with is better designed and better documented
than DOS ever was. I'm not disagreeing that you could do
what you wanted in DOS and you can't in Palm OS, but that's
life. I remember a huge mountain of things that just didn't
work in DOS and do in Palm OS.
