Re: code question

Almos true. I have used a version of APL (IBM 1139) where all operations where done left to right, including arithmetic.

There's a reason for that. If you look at the rules of formal logic,
you'll find that 'AND' has a lot of the same properties of
multiplication. It is associative, commutative, distributive and
idempotent.

I'd highly recommend some study of formal logic and/or Boolean algebra to anyone who writes code. A little bit of Boolean algebra can go a
long way in simplifying complex conditions on branching statements.
