Aspen Research Inc has enhanced its MS-DOS-based Mozart micro-to-mainframe application development system. Mozart version 1.1 enables developers to make mainframe applications Common User Access/SAA compliant without moving to OS/2 or rewriting application code, and allows them to add co-operative processing across several manufacturers’ hardware including IBM, Hewlett-Packard, DEC, and Prime Computer. Enhancements include support for AS/400s and asynchronous terminals, Expanded Memory System and improved memory management, support for the Japanese Kanji ideographic script, and a a self-running tutorial for the development environment. Since Mozart is hardware-independent, the company claims that it is suited to several markets including corporations, independent software vendors building mainstream business applications or vertical market products, network vendors, developers of emulator products, and system integrators or value-added resellers. Aspen is shipping Mozart 1.1, and is providing the upgrade free to all registered owners of Mozart version 1.0. The developer’s version is available direct from Aspen Research for $1,300, which includes software plus one year of free support and a formal training class. Runtime versions of Mozart are available from $200 to $500 based on quantities ordered.
