Operator IMP= (Implication and Assign)


Performs a bitwise-imp (implication) and assigns the result to a variable

Syntax:
declare operator Imp= ( byref lhs as T1, byref rhs as T2 )

Usage:
lhs Imp= rhs

Parameters:
lhs
The variable to assign to.
T1
Any numeric or boolean type.
rhs
The value to perform a bitwise-imp (implication) with lhs.
T2
Any numeric or boolean type.

Description:
This operator performs a bitwise-imp 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 imp rhs

Imp is a bitwise operator which is the same as (Not lhs) Or rhs. Imp= compares each bit of its operands, lhs and rhs, and if the bit in lhs is 0 or the bit in rhs is 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.

Examples:
Dim As UByte a = &b00110011
Dim As UByte b = &b01010101
a Imp= b
'' Result    a = &b11011101
Print Bin(a)
