The shift lock release is generally a button that is built onto the lever. It allows the driver to lock the gear lever into a particular option. For example, when the driver parks the car, he/she can switch the lever into the parking option and lock it there. The lever cannot be moved until the shift lock is released. The shift lock is typically a button on top or on the side of the lever.

Reaching definition. In compiler theory, a reaching definition for a given instruction is an earlier instruction whose target variable can reach (be assigned to) the given one without an intervening assignment. For example, in the following code: d1: y:= 3 d2: x:= y d1 is a reaching definition for d2. In the following, example, however: d1 : y := 3 d2 : y := 4 d3 : x := y d1 is no longer a reaching definition for d3, because d2 kills its reach: the value defined in d1 is no longer available and cannot reach d3
