To map an interface field

In the Interface Mapper, right-click an interface field on the Interface Fields pane and click Mapping from the context menu.
From the COBOL Field drop-down list, click a field you want to map to your interface field.
Click Add.
Click OK.

Note: By default, array fields appear with an asterisk, meaning that all occurrences are mapped. You can edit an array mapping, changing the asterisk to a subscript to point to a specific occurrence.
