7.4.12 Bitwise OR Operator (|)

Used to perform a bitwise OR on two expressions.
 

Syntax

result = expression1 | expression2

Arguments

result
Any variable.
expression1
Any expression.
expression2
Any expression.

Remarks

The | operator looks at the binary representation of the values of two expressions and does a bitwise OR operation on them. The result of this operation behaves as follows:
 

0101 (expression1)

1100 (expression2)

----

1101 (result)

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, see the Operator Behavior table.
