Re: Commitment Control (was: Modernizing applications (was: Explaining single level store tonon ipeople))

Nathan,

You may write outstanding code. And you may have something there on the
millionth of a second.

But you have to assume that some strange things may happen.

- Like, someone adds a check constraint on one of the tables and now
you're WRITE fails for a reason alien to your code.
- "File Full" message replied with a C.
- Someone does a bad code mod. Yes, you may think "s... to be them", but
I really don't want to go off on that tangent.
- Someone is doing an UPDDTA on a row you're trying to do a UPDATE on and
it's locked. Storm hits, UPS says you've got 10 minutes. Someone does an
ENDSBS *ALL *IMMED. Ok, you probably code around the record lock...
