Green Hills C++ has been validated using the Perennial Test Suites for C++ so developers can take advantage of commercial C++ class libraries and use existing C++ code. It includes the complex math and I/O stream class libraries in source code, royalty-free. The M++ class libraries are also available from Oasys. M++ handles matrices and arrays within C++. Green Hills C++ also supports the Classix libraries from Empathy.

Green Hills C++ will be integrated with a true C++ debugger, MULTI, also developed by Green Hills Software. MULTI is a source-level debugger that supports debugging of C++, C, FORTRAN and Pascal in an X Windows environment.

Oasys has integrated Green Hills C++ with cross development environments for 680x0, 88000, i860 and 386. It goes direct from source to assembly code, optimizing C++ source code without passing through a separate C compiler. The Oasys Assembler/Linker System processes C++ objects that are produced by the Green Hills Cross C++ compiler. No post-link step is required since the Assembler/Linker is fully aware of constructor and destructor functions in C++.

Oasys provides Green Hills C++ on UNIX-based hosts, including Sun-4 SPARC, Sun-3, DECstation/systems, IBM RS6000, 386 UNIX/System V, and 88open compliant machines beginning at $1,400. Green Hills Cross C++ sells starting at $2,200 with a special offer for the C++ compiler and Assembler/Linker System starting at $3,200.

The XBD source level cross debugger lets the user debug from the host computer system, while the program runs in real-time in the microprocessor. XDB allows the user to: set breakpoints; single step at the C or assembly level; display source code, register and stack information; set monitor and modify data; define macros and aliases; record and play back debugging sessions; simulate target I/O; and access pop-up windows for status information and on-line help.

XDB is available for three execution environments: XDBice is integrated with in-circuit emulators, XDBrom is integrated and bundled with a configurable ROM monitor, and XDBsim is bundled with a 68000-based simulator board.

These InterTool software packages sell beginning at $1,975 for the Compiler/ Assembler/Utilities toolkit, $1,650 for XDBice, $2,500 for the XDBrom debugger and the ROM Monitor, and $2,400 for the XDBsim debugger and the simulation board. All prices are for the IBM PC host computer.

The classes in QualBase for DOS are object-oriented in design and implementation. Maximum efficiency is achieved by minimizing use of virtual functions, and maximizing use of inline functions. Extendibility is achieve by providing better cominized base classes and several basic variations from which the designer can choose.

Qualbase for DOS provides several classes specifically implemented for DOS as well as fundamental classes. A partial list of classes includes arrays, lists, strings, interrupts, registers, binary trees, bit vectors, and queues. Pseudotemplates are provided for arrays, lists, queues and binary trees.

The suggested introductory price of QualBase for DOS is $85, and includes documentation, source code, as well as a PolyDoc/SourceDoc library for online help. Zortech or Borland object libraries are available. PolyDoc/SourceDoc are not included in the QualBase product.

For more information, contact Qualware at 1381 S.E. Sycamore Ave., Tustin, CA 92680. (714) 259-1322.

Features of the libraries include: variations on malloc() that allow very fast heap memory allocation or that efficiently use memory; functions that write heap data or a heap map to the screen, printer, or a disk file; near and far heap buffer manipulation functions; versions of realloc() that maximize block resizing likelihood without copying bytes, and guarantee that new bytes added to a block will be set to zero; super fast buffered disk I/O functions for linked list data; quickly implement a best fit mallock(); write disk data to a linked list in memory without increasing memory fragmentation; limit the size of the far heap, and reserve memory within the program block from far heap memory allocation functions.

C-Heap sells for $429. For more information, contact Library Technologies, P.O. Box 56031, Madison, WI 53705-9331. (800) 767-4214.

GraphLink builds large images on systems which have only a small amount of conventional memory available, but also takes full advantage of machines with megabytes of expanded memory.

A Screen Capture module gives programmers the ability to print high resolution graphics to existing programs by adding as few as three additional lines of code.

Stroked fonts and high quality filled outline fonts are provided. They can be scaled to any size, drawn at any angle, and rendered in italics and boldface. A mouse-based font editor is included to edit character shapes or create special symbols.

New printer drivers can be added to GraphLink's printer driver database by editing a table containing escape sequences and numerical, logical, and descriptive information relevant to the printer. Drivers are included for a variety of laser, inkjet, and dot matrix printers.

The library implements PostScript calls at three levels of support. For experienced PostScript programmersfunctions to add PostScript procedures and call the primitive PostScript procedures directly. For developers with some familiarity with the language a mid-level interface to handle text, graphics, loops, etc. through a familiar C language interface. For programmers unfamiliar with PostScript, a high-level interface that takes care of all of the PostScript and allows printing ASCII text just as if sending to a TTY device.

Through interplay between the C language function calls and the procedures, definitions, and variables within the PostScript document, c_pslib gives the programmer complete control over the output without tracking of current points, line widths, gray levels, etc.

The introductory offer includes Turbo C v2.0 and Microsoft C v6.0 libraries plus ANSI- and K&R-compatible source code. Separate UNIX versions are also available.

Features include a complete set of graphics functions, paragraph and text functions, ASCII text support for simple line-oriented reports, downloadable font support, conforms to Adobe structured comment conventions, and conditional compilation macros for K&R compilers.
