The logic operators AND , OR , NAND , NOR , XOR, XNOR and NOT are defined for the predefined data types bit and boolean . They can also be used for one-dimensional array-types ( Array ) whose elements are of the type bit or boolean . If the operators AND , OR , NAND , NOR , XOR and XNOR are to be used in this last case the following has to be taken into consideration:
Both arrays have to have the same length.
The operation is carried out with the corresponding elements of both arrays.
The result is a array which has the same field depth as the left operand.
Basically the same is valid for the operator NOT , however, the operation is carried out with every individual element of the array. All binary logic operators have the lowest priority. The unary operator NOT has top priority.

T stands for true (type boolean ), '1' (type bit ).
F stands for false (type boolean ), '0' (type bit ).
