Figure 1–2: Progress Interactions Using the System Clipboard

The dotted box emphasizes that, from the user’s viewpoint, the clipboard is essentially invisible.
Progress supports clipboard interactions with other graphical applications in the Windows environments. In character mode, Progress supports clipboard interactions between fields in a single Progress application. Using the CLIPBOARD system handle and an appropriate set of user-interface triggers, you can define the response of your Progress application to the standard clipboard operations on your system. For example, you can eliminate cut operations (that remove data) and provide only copy and paste; or you can specify how the data is transferred, whether all or part of it is transferred, and where it goes when it is pasted into your Progress application.
