The Value List Box

The Value list box (see figure) is a small feature, but it appears so many places in IPA Designer that it merits its own explanation.

The Value list box lets you enter a value in three different ways. You can also choose not to set the value:

• Literal: This displays a text box in which you can type the value.

• Variable: This lets you select a process variable from which to get the value. When the process runs, it will use the current value of the variable you select.

• Calculation: This lets you create a calculation whose result will be used as the value. To create the calculation, you will use the Calculation Editor dialog box.

• Not Set: This leaves the variable with a null (not set) value.

Tip: When the Value list box is open, you can quickly select one of its list choices by pressing L (Literal), V (Variable), or C (Calculation).
