Performs a bitwise-or (inclusive disjunction) and assigns the result to a variable

Operatorsoperatordocumented

Syntax

Declare Operator Or= ( ByRef lhs As T1, ByRef rhs As T2 )

Parameters

Name		Description
`lhs`		The variable to assign to.
`T1`		Any numeric or boolean type.
`rhs`		The value to perform a bitwise-or (inclusive disjunction) with
`lhs`		.
`T2`		Any numeric or boolean type.

Description

This operator performs a bitwise-or and assigns the result to a variable (for conversion of a boolean to an integer, false or true boolean value becomes 0 or -1 integer value). It is functionally equivalent to:

lhs = lhs Or rhs

Or= compares each bit of its operands, lhs and rhs, and if either bits are 1, then the corresponding bit in the first operand, lhs, is set to 1, otherwise it is set to 0.

This operator can be overloaded for user-defined types as a member Operator using the appropriate syntax.

Note: Similarly to the operator '=[>]' (assign), the alternative symbol 'Or=>' can be also used.

Remarks

Usage



lhs Or= rhs

Dialect Differences

In the -lang qb dialect, this operator cannot be overloaded.

Example

Dim As UByte a = &b00110011

Dim As UByte b = &b01010101

a Or= b

'' Result    a = &b01110111

Print Bin(a)
