Boolean (logical) operators

Logical operators can only be used with arguments that can be evaluated to a boolean. The result of a logical operation is a boolean. The following table shows the logical operators that are available in AL.

Boolean operators

As the following table shows, the not operator is a unary prefix operator. This means that it takes only one argument and is placed in front of the argument. The and, or, and xor operators are binary infix operators; they take two arguments and are placed between the corresponding arguments.

Operator	Name	Expression	Resulting data type
not	Logical negation	not bool	Boolean
and	Logical and	bool1 and bool2	Boolean
or	Logical or	bool1 or bool2	Boolean
xor	Exclusive logical or	bool1 xor bool2	Boolean
