Boolean Operators
=	a = b		a is equal to b
<	a < b		a is less than b
<=	a <= b		a is less than or equal to b
>	a > b		a is less than b
>=	a >= b		a is greater than or equal to b
<>	a <> b		a is not equal to b

AND - both conditions must be met for the test to evaluate to TRUE.

OR - at least one of the conditions must be met for the test to evaluate to TRUE.

XOR - only one of the conditions must be met for the test to evaluate to TRUE.

NOT - reverses the value.
