After you have defined the Cursor List object addresses, you are ready to
begin creating the object lists.

Step 2: Create the Object Lists

To monitor and control all the stations of the Automobile Luxury Options
Assembly, you will create these five object lists:

Two Numeric Data Display Object Lists

Two Multi-State Indicator Object Lists

One Local Message Object List

In this application, each object list serves a different function. These
functions are outlined below.

Assembly Stations

A Numeric Display Object List displays the station number of the
automobile assembly sequence. The station numbers range from 1 to 57.
Because there are five visible states configured, there will always be five
stations visible. The values displayed depend on where the cursor moves
and the number of preview states selected.
