Although HaL Computer Systems Ltd hasn't much that's tangible to show for its years of hardware development efforts, its coding unit, HaL Software Systems is showing the way to go. With a graphical Distributed Computing Environment administration tool already under its belt, the Austin, Texas concern has a new unified system for navigating, retrieving and displaying information from a variety of sources including Standardised Generalised Mark-up Language and World Wide Web documents and relational databases. Now in beta test, Olias Browser will be up on Sun Microsystems Inc workstations first from May, under other Unixes from the third quarter, and under Microsoft Corp Windows early next year. Text is dynamically formatted with images, graphics and tables and the full-text search system comes with an expandable and collapsible table of contents and hypertext links. Olias Build Tools compile Mark-up Language documents into a library format for storage and searching, which can be distributed on CD-ROM for viewing with Olias Browser. A gateway to other sources such as World Wide Web is provided by Olias Remote Information Broker, while Olias Filter development Kit enables other kinds of existing documents to be migrated into Standardised Generalised Mark-up Language for electronic delivery and viewing under the browser. Build Tools and Remote Information Broker are due in the third quarter, the Filter Development Kit by year-end. Olias Browser is $100 per user, Build Tools are $7,500 for up to four users, the Broker is $50 per user and the development kit $5,000 per site licence.
