Continuing its efforts to make object-oriented technology accessible to developers using personal computers, Scotts Valley, California-based Borland International Inc has come out with version 2.0 of the Paradox Engine, which when combined with Borland’s new C++ enables developers to build object-oriented programs that incorporate the Engine technology. The Paradox Engine provides Windows application programmers with the ability to exploit Windows 3.0 memory management features, such as multi-session, multi-user and concurrent access to Paradox data via the Engine’s Dynamic Link Library. The Paradox Engine provides access to file locking, record locking and password protection features of Paradox. Developers can explictly manipulate the locking mechanisms in addition to built-in automatic locking routines to achieve concurrent access to Paradox data files. Other features include primary and secondary index access, searching and error handling. The Engine retails for $500, which includes an unlimited runtime licence for applications developed using the engine. However, it will carry an introductory price in the US of $100 until June 30, 1991. Upgrades from the existing version go for $80 until June 30, 1991 and $100 thereafter.
