The Subscript Range
First we need to make a new variable that describes the concept of having different tasks. This is called the Subscript Range and a suitable name in this case is task.
| Ø | Click on the Subscript Control button on the Toolbar. The Subscript Control opens: |
| Ø | Click on the New… button, in the dialog box type the name task then press Enter. |
The Equation Editor opens to display the incomplete equation for task. This is a Subscript Range and it describes the three tasks: design, prototype, and build. The range task does not equal these tasks, it represents the tasks. Note that the Equation Editor displays the Subscript symbol :left of the equation editing box.
| Ø | Fill in the three tasks, as below (you don't need to type task : that is already entered) then click on the OK button. |
| task : |
| design, prototype, build |
The three tasks should now be showing in the Subscript Control. Note that the subscript range task and the three subscripts do not appear in the sketch. The subscript range and subscripts are part of the definition of the model, not part of the diagrammatic structure.
