Description

Used to perform a bitwise OR 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 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 will have a 1 in that digit. Otherwise, the result will have a 0 in that digit.

For information on when a run-time error is generated by the |= operator, please see the Bitwise Operators table.
