Quite often this operator is used in combination with other comparison operators, such as in
the following example.
IF (Y == 20) AND (Z == 100)
This example evaluates the result of
Boolean AND operator returns
Boolean AND has an assignment form,
operand and the result destination. For example,
X AND= True
Here, the value of
Boolean result (
AND may also be used within expressions for intermediate results; see Intermediate
Assignments, page 253.
Be careful not to get Boolean AND ‘
for comparison purposes while Bitwise AND is for bit manipulation (see page 269).
Boolean OR ‘
The Boolean OR ‘

X := Y OR Z
The above example compares the value of

promotes each of the two values to -1 if they are non-zero, making any value, other than 0, a -
