Logic: true false and or not xor

Logic:

Logic operators perform boolean operations on values on the boolean stack, popping them off the stack in the process and pushing the result onto the stack, either true or false. The result obviously will depend upong the operator was used and the boolean values on the stack at the time.

Energy Cost:

As of version 2.4, you can set the Energy cost per logic command executed if you so choose. The default cost is 0.
