Support X11 Release 4 extends the choices available to programmers developing applications with C++. Programmers can perform all coding tasks in one environment and move freely between windows on the screen.

Objectworks\C++ Release 2 is designed to help C++ programmers benefit from object-oriented technology. Release 2 enables users to work with Objectwork\C++ with traditional UNIX tools, such as VI and emac editors and source code control systems. With these tools, programmers can create, understand, find and reuse existing C++ code, whether they are the original developers or not. Release 2 can support large system development and incorporates the AT&T C++ Language System, Release 2.1.

ParcPlace also offers Objectkit\C++, a collection of reusable C++ class libraries, which includes AT&T's Standard Library and Standard Library Extension.

Objectworks\C++ under X Window is available for the Sun-3 and SPARCstation platforms. It requires 12Mb of memory and is priced at $3,000 in the United States and Canada. Objectkit\C++ is priced at $500. Full technical support services, including a customer hotline, upgrades to new software releases, an electronic bulletin board and regular newsletters are offered. In-house and on-site training courses are available, covering introductory through advanced level object-oriented methodology and programming.

Capsule consists of library of C++ objects that supplies the object-oriented software engineer with general purpose data structures. The classes in Capsule are delivered as AT&T v2.1 C++ source modules and include reusable container objects, employing C++ encapsulation, inheritance, and polymorphism.

Capsule includes general purpose container base classes, application classes, and stand-alone applications derived from the base classes. The base classes encapsulate flexible data structures and program blocks for implementing linked lists, circular lists, stacks, queues, keys, data, and hash tables, binary trees, graphs, error detection, and registry.

Capsule includes two special classes to support error registry and detection, allowing applications to register objects so Capsule will report erroneous class usage at runtime.

Microtec Research licenses the Capsule library on a per-CPU basis and supplies library package as AT&T v2.1 compatible C++ source code files. The Capsule library is $495 per CPU. Annual software maintenance is available for $250 per license. For more information, contact Microtec Research, 2350 Mission College Blvd., Santa Clara, CA 95054, (800) 950-5554; FAX (408) 982-8266.

Promula.Fortran supports both the FORTRAN 6 and the FORTRAN 77 standards and almost all existing FORTRAN dialects: VAX VMS, IBM VS, PDP-11, PRIME FTN and F77, SUN F77, and Honeywell FORTRAN. It also supports a number of FORTRAN 90 features, such as structures and pointer variables. Moreover, it has a dialect definition file that allows you to configure the compiler for features not included in the default dialect definition.

No matter how old or extended your FORTRAN dialect is, Promula will process it by first compiling it to C. Promula.Fortran translates FORTRAN code to clean, portable, and maintainable C code while allowing extensive control over the translation process. The resultant C code can then be compiled via any standard C compiler and linked with the Promula.Fortran runtime library to produce efficient executable code, which produces the same results on a target platform as the original code on the source platform.

Promula. Fortran is available for several platforms, including IBM PC, Apple Macintosh, VAX/VMS, VAX/Ultrix, SUN/UNIX, IBM/AIX, and other UNIX workstations, as well as IBM mainframes. Prices start at $995 for a single-user PC license. Multi-user, cross-compiler, and multi-platform licenses are also available. For more information, contact Promula Development Corporation, 3620 North High St., Suite 301, Columbus, OH 43214, (614) 263-5454.

CodeWatch windowing provides easy interaction with the debugger. Developers have access to CodeWatch commands through menus and dialogs, and they can choose either CodeWatch/X or CodeWatch/CH.

CodeWatch/X displays a graphical-based interface that uses all the capabilities of the Motif user interface and X Window. The Source window displays the current source file, allowing the user to scroll, search, and set breakpoints. The Command window allows the user to type in commands that are saved and can be viewed during the debugging session by scrolling the window. User program output goes to the terminal window. User program output goes to the terminal window from which CodeWatch/X is invoked.

CodeWatch/CH provides a character-based interface that can run on any ASCII terminal, without a graphical windowing system. CodeWatch/CH offers the same two windows as CodeWatch/X: Source and Command. It also provides a program output window to display user program output.

CodeWatch v5.0 supports LPI's FORTRAN, C, PL/I, Cobol, BASIC, and Pascal languages, initially on 386, 486, SPARC, and Sun 3 architectures running UNIX. For more information, contact Language Processors, 959 Concord St., Framingham, MA 01701-4613, (508) 626-0006; FAX (508) 626-2221.

JAM/Presentation interface for Motif allows developers to present their forms or objects in graphical, character or block-mode without recompilation. For example, a form drawn in Motif and saved on a file server can be commonly accessed and used by character-based devices without any changes or reconfiguration.

JAM/Presentation supports Motif widgets. All forms run as separate Motif windows, and data entry fields use Motif text widgets. Menus, radio buttons, and check lists use standard OSF Motif widgets. Error messages are handled by a standard error dialogue box, and support is provided for proportional fonts. The interface also provides complete Motif-compliant mouse support.

JAM provides built-in character and field-level edits and validations, sibling windows, and parallel scrolling arrays. JAM's extended 4GL supports 13 different RDBMSs, and it also supports graphical or binary data objects stored in those databases.

JAM/Presentation interface for Motif is priced from $395 to $1,995. For more information, contact JYACC, 116 John St., New York, NY 10038, (212) 267-7722; FAX (212) 608-6753.

The CommBlok library is available for Microsoft C and Turbo C. The library sells for $299 and includes sources code. For more information, contact Drumlin, 1011 Grand Central Ave., Glendale, CA 91201, (818) 244-4600; FAX (818) 244-4246.

XDB 5.0 provides the following features through a multi-window user interface: the ability to display source code, registers and stack information, set software breakpoints, single step at the C or assembly level, 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 online help.

Prices begin at $1,975 for XDB 5.0 hosted on the IBM PC. Full toolkits of compilers, assemblers, utilities, plus XDB 5.0 are $4,400. For more information, contact Intermetrics, 733 Concord Ave., Cambridge, MA 02138-1002, (617) 661-0072; (617) 828-2843.

High-level language or assembly language variables can be displayed or modified in their declared format. Integers, longs, chars, floating point, and complex variables, and even structures and unions are correctly displayed and can be set to any legal value. Breakpoints can be set on high-level instructions, and the program single-stepped through high-level lines as well as processor instructions.

Locate and TDREM supply the technical interfaces needed to use in-circuit emulators, EPROM programmers, and the Borland Turbo debugger with these compilers.

Locate accepts the relocatable output from Microsoft C, Turbo C, or Turbo C++ and converts it to an absolute format with optional debugging information. Features offered in the new release are full C++ support, automatic peripheral register initialization, address space partitioning, and full debug information control.

TDREM emulates the Turbo Debugger remote interface, making a full set of Turbo Debugger capabilities available to observe and control the application executing on the target system. These capabilities include the ability to set complex breakpoints, and inspect and modify data structures.
