Operator Xor= (Exclusive Disjunction And Assign)

Performs a bitwise-xor (exclusive disjunction) and assigns the result to a 
variable

Syntax
	KeyPgDeclareDeclare KeyPgOperatorOperator Xor= ( KeyPgByrefByRef lhs KeyPgAsAs T1, KeyPgByrefByRef rhs KeyPgAsAs T2 )

Usage
	lhs Xor= rhs

Parameters
	lhs
		The variable to assign to.
	T1
		Any numeric or boolean type.
	rhs
		The value to perform a bitwise-xor (exclusive or) 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 KeyPgOpXorXor rhs

	Xor= compares each bit of its operands, lhs and rhs, and if both bits 
	are the same (both 1 or both 0), then the corresponding bit in the first 
	operand, lhs, is set to 0, otherwise it is set to 1.

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

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

Example
	Dim As UByte a = &b00110011
	Dim As UByte b = &b01010101
	a Xor= b
	'' Result    a = &b01100110
	Print Bin(a)

Dialect Differences
	* In the CompilerOptlang-lang qb dialect, this operator cannot be overloaded.

Differences from QB
	* New to FreeBASIC
