Effect

Performs a bitwise XOR-operation (logical exclusive or) between two expressions.

The bit is set if one bit is set and the other one isn't:

0 XOR 0 = 0
0 XOR 1 = 1
1 XOR 0 = 1
1 XOR 1 = 0

Syntax

<Value> XOR <Value>

Parameter

<Value> is a value between -32768 and 32767. It can also be a a numeric variable, a mathematical expression or expression from a condition.

Notes:
- If you use binary expressions, it is best to put the first expression in parenthesis to avoid the bug in interpreter that causes a syntax error. This problem does not happen with decimal, hexadecimal or octal expressions.
- When the expression performed in a condition (IF...THEN...ELSE or IF...GOTO...ELSE) if the result of the whole expression is zero the value is taken as false, otherwise it's taken as true.
