YENGShortcircuit

Operators &&& and ||| are AND and OR logic operators that evaluate the expression to their left and will only evaluate the expression to their right, if the one at left does not define the result.

Make sure to add yoptions; to the second line of the script, usually line number 1 starting from 0.

&&& will not evaluate right side if left is FALSE
||| will not evaluate right side if left is TRUE

Care using () to make complex expressions more clear.
