Challenge: Identify ways to use XOR logical operator

[Moneo]

In the Challenge topic re Recursion, we also saw the following use of XOR.

Code:

REM Generate Gray Code bytes; i.e. values in range from 0 to 255.
DEFINT A-Z
FOR X=0 TO 255
        GRAY = X XOR (INT(X/2))
        rem Print or output the Gray Code value in GRAY.
NEXT X
