# Bitwise OR Assignment Operator (|=)

Performs a bitwise OR on the value of a variable and the value of an expression and assigns the result to the variable.

*result* **|=** *expression*

#### Arguments

*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 OR operation on them. The result of this operation behaves like this:

0101 (result)
1100 (expression)
----
1101 (output)

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