Language Reference 

Description
Used to perform a bitwise OR on two expressions.

Syntax
result = expression1 | expression2

The | operator syntax has these parts:

Part Description
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, please see the Bitwise Operators table.
