This release addresses MS-DOS memory restrictions with a combination of existing MS-DOS extender technology and Zortech's new Virtual Code Management (VCM) technology and new versions of the C++ debugger which have minimal memory overhead. VCM allows MS-DOS applications to contain up to 4MB of program code and still run in real mode. The VCM system does not require any changes to application source code (except assembly language). See page 37 in this issue for a detailed technical description of VCM.

This release includes a version of the compiler incorporating MS-DOS extender technology, allowing the compiler to use extended memory when compiling applications with large and complex class hierarchies. The compiler can also be used to develop applications using the Rational Systems MS-DOS extender, which may be purchased separately. Such applications can exceed the 640K limit on 80286/386/486 systems with extended memory.

The use of the same technology in the debugger allows it to relocate itself into extended memory, allowing much larger programs to be debugged. A virtual 8086 mode debugger is provided (for 80386 systems) which requires almost no conventional memory. A facility for remote debugging via the serial port has been added.

Version 2.1 also features a 20 percent improvement in compilation speed, a new program development environment with a source level browser, multi-file editing and integrated compilation, improved code generation, refined code optimization, and a completely revised and expanded C++ Tools.

Pricing on v2.1 is unchanged. Special upgrade pricing is available. Contact Zortech Inc., 4-C Gill Street, Woburn, MA 01801. (800) 848-8408 or (617) 646-6703; FAX (617)643-7969.

The new version supports large, multi-user development projects with a new central database, a graphics-based database management facility, and individualized working environments. Statemate's prototyping facility now generates C code in addition to Ada. Other new features include: an enhanced ability to handle hierarchical models; an improved simulation control language that permits playback of simulation scenarios and dynamic analysis results; and the ability to handle user-written code as part of the Statemate simulation.

Dataport, a new module in Statemate 3.0, provides a programming interface for extracting information from the Statemate model. It facilitates access to Statemate from other software development tools.

Statemate 3.0 operates on several new platform, operating systems and environments. New platforms are DECstation and Sun4. New operating systems are ULTRIX 3.2, Domain/OS SR 10.2, and Sun OS 4. New environments are DECwindows and X Window.

Sbrowse integrates with the user's editor; you can call Sbrowse from within the editor, stack Sbrowse and editor calls, or switch back and forth between different Sbrowse invocations.

Sbrowse answers questions about variables, preprocessor symbols, functions, operators, aggregates, types, enumerations, classes, structs, unions, error messages, and source files from a symbol index that it constructs the first time it is used on the source files. It reconstructs the symbol index only if the source file is changed.
