[next] [previous] [contents] [full-page]

Access to DEC's Bookreader format documentation (and any generated internally) is provided in the WASD hypertext environment via two integrated scripts, HyperReader, which reads the books, and HyperShelf, which reads the Library and Shelf structures.

The HyperReader and HyperShelf scripts are automatically activated when the document file's extension is ".DECW$BOOK" and ".DECW$BOOKSHELF" respectively. Alternatively, the respective scripts may be explicitly specified (but the ability to provide a relative specification is lost).

If the server system supports Bookreader documentation collection the following link will provide an online demonstration:
