If a field was created with a declared variable in OpenROAD Workbench, you access the field's data value by using the name of the field as a variable.

For example, assume that salary is the name of a field with data type money and dollars is a variable declared with the same data type. The following statements are valid:

You cannot perform these calculations as easily when working with a dynamically created field. To access the value of a dynamically created field, you must invoke a method on the field or use a dynamic expression (DynExpr).

For a discussion of accessing values in dynamically created fields, see How You Can Set and Get Simple Field Values (see How You Can Set and Get Simple Field Values) and How You Can Access Individual Cells of a Dynamic Table Field (see How You Can Access Individual Cells of a Dynamic Table Field).
