Used to perform a bitwise OR on an expression.
result |= expression
The |= operator syntax has these parts:
Part Description result Any variable. expression Any expression.
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.
For information on when a run-time error is generated by the |= operator, see the Operator Behavior table.
