Now suppose we want to make a case using the jib hook instead of the main hook. SetCrane allows that too:

Now DB PutCraneCase "Lift 2" stores it as a new case.

As with the other Get...Case commands, you get a listing of all cases when the case identification is omitted. In this simple example DB GetCraneCase results in this:
