Description

Used to perform a bitwise AND on an expression.

Syntax

result &= expression

The &= operator syntax has these parts:

Part	Description
result	Any variable.
expression	Any expression.

Remarks

Using this operator is exactly the same as specifying:

result = result & expression

The &= operator looks at the binary representation of the values of result and expression and does a bitwise AND operation on them. The output of this operation behaves like this:

0101    (result)
1100    (expression)
----
0100    (output)

Any time both of the expressions have a 1 in a digit, the result has a 1 in that digit. Otherwise, the result has a 0 in that digit.

For information on when a run-time error is generated by the &= operator, see the Operator Behavior table.
