Ken, old chap, please do us a favour, and don't leave the "--" line in the top
of your postings - it's _supposed_ to be used as a signature-separator, and as
a result, when I'm trying to reply to your postings, the newsreader I'm using
tries to automatically strip your signature, and I get the above as the
_whole_ of your quoted post. I understand you're fighting against Outlook,
and trying to avoid top-posting, which is a great goal. I'm told that there
are other tools you can get that can help with doing proper signature
placement.

Now, on to what I wanted to say on your post, brought over by manual cut and
paste:

Some programmers here will remember that there is a debugging tool or two that
operates (in part) by checking the range of parameters submitted to Windows
API functions. But those programmers that have used it will recall that it
makes programs run about three times slower than normal, and it's really only
appropriate to run these tests for problems that would show up inside of five
minutes of normal operation, because otherwise the tester / debugger will get
bored waiting for the results. So, even if the compiler were to insert
checking code (or if programmers were to check all parameters), it's clear
that software still isn't running fast enough to do so in a released version.

Alun.
