When writing a custom program or using Results (where you create ad hoc reports), it is useful to have a list of all files where a certain field is referenced. Use Find Fields to produce this list.
Select Find Fields from the System menu to display the Find Fields Report screen.
Select Add and enter a text string for which you want to search. You can press F2 to select from a list of exact field names.
Select Continue to produce the list. The list can be viewed and printed like other reports.
