Burlingame, California-based Mozart Systems Corp, formerly known as Aspen Research Inc, says that the enhanced version of its micro-to-mainframe application development system bridges the gap between MS-DOS and OS/2. The company claims that Mozart Version 2.0 will enable developers to build co-operative processing applications that can be directly transported between MS-DOS and OS/2 Extended Edition without any modification. Version 2.0 of the Mozart application development system will be available for OS/2 Extended Presentation Manager, MS-DOS graphics-based and MS-DOS character-based development environments. Other enhancements include additional Systems Application Architecture Common User Access standards compliance and a relational database management system interface via embedded SQL. It supports native Presentation Manager applications using Presentation Manager-supplied CUA objects, exploits OS/2 Extended interprocess communications facilities and runs as a multi-threaded OS/2 application. The MS-DOS graphics version of Mozart provides presentation-level graphic icons and inclusion of graphic images without requiring additional software. A new Mozart MS-DOS Extended Memory version allows developers to go beyond the traditional MS-DOS 640Kb memory barrier and load multiple applications simultaneously under MS-DOS equipment. Mozart will support IBM’s Advanced Program-to-Program Communications via the Common Programming Interface Communications Specification, and by LU6.2 later this year. Mozart currently supports APPC-like data transfer with existing LU2 screen interfaces. The single developer’s versions of Mozart for MS-DOS and OS/2 Extended cost $5,000 and $6,250, respectively. Runtime licences are $500 and $625, and both are available this quarter.
