Clicking on the Add button opens the Add coverage data file dialog box shown below.

Figure 5.98 Add coverage data file dialog box

Use this dialog box to specify the coverage information file you want to load. You can also specify a mode of loading and

offset for each file you load.

The only file-name extension allowed is ".cdv". An error message will appear if any other extension is entered.

The files you add will be listed in the Load Coverage Data dialog box. The files will be loaded in the order in which they are

listed. If necessary, use the Move Up or Move Down button to change the order.
