Operator Or= (Inclusive Disjunction And Assign)
Performs a bitwise-or (inclusive disjunction) and assigns the result to a variable
Syntax
`
Declare Operator Or= ( ByRef lhs As T1, ByRef rhs As T2 )
`
Usage
`
lhs Or= rhs
`
Parameters
`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.
Example
`
Dim As UByte a = &b00110011
Dim As UByte b = &b01010101
a Or= b
'' Result a = &b01110111
Print Bin(a)
`
Dialect Differences

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