The Default Device Design

The default device design for the Edit Race and Entries function should look like the panel below. Note that the subfile control (header) is positioned at the top with the subfile record (detail) below. The common key of the two file formats displays only in the subfile control and acts as an implicit restrictor parameter to the subfile detail records.

Note also the virtual fields Course name, Horse name, and Jockey name. If you had

not explicitly added these fields to the formats of the SPN access path, they would not appear on this display.
