May.25.2020 -- CAlive to introduce the !() negating logic operator

[Rick C. Hodgin]

CAlive will introduce the !() syntax to negate logic tests for formal commands if and while.  This is the equivalent of doing a logic test and then branching on the opposite condition.

    // Traditional code, test the logic and negates the entire expression within the logic test

    if (!(a == b && c == d))

        // Code here

    // With the negating logic operator, you can code the original logic and invert it outside the logic test

    if !(a == b && c == d)

        // Code here

Note:  This is a sweeping negation.  It will invert the entire result of the logic test.
