RE: notted boolean expressions (was: output specs and indicators)

Scott,

I thought I had always grouped my expressions well when warrented, but I'm
still unclear.  does the phrase in your post at the bottom mean that if ANY
ONE of the indicators are off, the entire expression is true?

or does it mean that if 99 is off and 98 and 98 are on, the expression is
true?

what about:

    if    not *in10 and not *in11

does this mean both 10 and 11 must be off for the expression to be true? or
somthing else?

Thanks,

Rick
-----original message------
This means that in the following expressino the NOT is applied against
*IN99
before doing the AND operations.
              if           NOT *IN99 and *IN98 and *IN97

It is my preference to use parens to always indicate the grouping I want to
occur.  This makes it easier to code and to read because a person doesn't
have to stop and think about the precedence rules.  This becomes more
important the more complex an expression becomes.
