PRODUCT NAME: | Compaq C++ Version 5.6C for OpenVMS VAX | SPD 37.39.12

December 1999

# DESCRIPTION

Compaq C++ for OpenVMS VAX is a native programming language product that generates optimized position-independent code without employing an intermediate translation to C. Compaq C++ is based on The Annotated C++ Reference Manual (ARM), by Ellis and Stroustrup. In addition to ARM, Compaq C++ supports CFRONT and MS dialects.

Compaq C++ includes:

- A subset of the ANSI C++ Standard Library, including the string library, numeric_limits, auto_ptr, standard exception classes, complex math library, and the Standard Template Library (STL) updated to a subset of the September 1996 ANSI C++ draft. Portions of the ANSI C++ Standard Library have been implemented using source licensed from and copyrighted by Rogue Wave Software, Inc.
- A Compaq C++ Class Library containing the following packages: iostream, complex, generic, objection, stopwatch, string, task, messages, and vector.
- ANSI/ISO C header files enhanced for use with the Compaq C++ compiler. These headers are currently packaged with Compaq C++. Packaging of the headers is subject to change as they become available in subsequent releases of related products.
- Features to facilitate porting to Compaq C++ from other C++ implementations. The /STANDARD=CFRONT option relaxes error checking for better compatibility with C++ compilers based on the AT&T "cfront" translator. The /STANDARD=MS option provides better compatibility with Microsoft's Visual C++tm.
- Automatic instantiation of templates
- A name demangler that enables other tools (besides the compiler and debugger) to present demangled names to the user.

Compaq C++ documentation provides comprehensive reference and usage information for all product components. Online help is provided with the software, and HTML files are provided for the release notes and some of the product manuals for use with a web browser.

HTML file are also provided on the Layered Products CD-ROM for the following manuals:

- Using Compaq C++ for OpenVMS VAX
- Compaq C++ Installation Guide for OpenVMS VAX
- Compaq C++ Class Library Reference Manual

Hardcopy documentation is available by ordering the separate software documentation kit. The hardcopy documentation also includes a copy of an authoritative book on C++, the C++ Programming Language, 3rd edition, by Bjarne Stroustrup, and a copy of the STL Tutorial and Reference Guide, by David R. Musser and Atul Saini.

Features

- Fast compilation and increased code optimization by directly translating C++ source programs to OpenVMS object files
- Extensive global and local optimizations of generated code for increased performance under OpenVMS
- Option for running only the preprocessor phase of compilation
- Pragmas to control compiler options
  - Pragmas to control extern models, sharing of data between concurrent processes, and structure member alignment
- Separate and combined compilation capabilities
- Compiler-generated listing file, including optional:
  - Machine code
  - Macro expansion
  - Compilation statistics
- Data types for numeric, nonnumeric, and systems programming:
  - Compaq C++ supports 8, 16, 32-bit signed and unsigned integers.
  - Compaq C++ supports 32-bit and 64-bit VAX floating-point data types. The VAX floating-point formats include D-float and G-float and are user selectable.
- Integration into the Program Development Environment:
  - Generation of debug and traceback records for OpenVMS VAX
  - Conforms to the OpenVMS calling standard
  - Access to the OpenVMS Run-time Library for general purpose routines and support of multi-language environments
  - Access to the data management facilities of OpenVMS RMS (Record Management Services)
  - Ability to package C++ code as shareable libraries
  - Ability to use additional class libraries. The Compaq C++ compiler supports logical name search lists in conjunction with the preprocessor directive #include.
  - Support for DIGITAL Language-Sensitive Editor to provide error diagnostics to the Editor

Run-Time Library for C applications

The complete Compaq C Run-Time Library needed for use with Compaq C++ is distributed with the operating system. The Compaq C Run-Time Library provides routines to perform input/output, character and string handling, mathematical computations, memory allocation, and emulation of selected UNIX® features. These routines are provided both in shared image and object module library form. Compaq C++ Class Library

The Compaq C++ Class-Library Run-Time components are distributed with the operating system. The Compaq C++ Class Library provides the following packages: iostream, complex, generic, objection, stopwatch, string, task, message and vector.

Run-time Library Redistribution

The Compaq C++ kit may include run-time library components in shareable image, object library, or saveset form. Compaq grants the user a nonexclusive royalty-free worldwide right to reproduce and distribute these Run-Time Libraries and savesets provided that the user:

- distributes them only in conjunction with and as a part of the users's software application product, which is designed to operate in the Compaq OpenVMS environment;
- distributes savesets in their entirety along with their accompanying installation documentation.
- does not use Compaq's name, logo, or trademarks to market the user's software application product;
- includes Compaq's copyright notice for Compaq C++ on one of the following:

  > a. the user's product disk label
  > b. each copy of the application
  > c. the title or copyright page of the documentation for the software application product

- agrees to indemnify, hold harmless, and defend Compaq from and against any claims or lawsuits, including attorney's fees, that arise or result from the use or distribution of the software application product. Except as expressly provided herein, Compaq grants no implied or express license under any of its patents, copyrights, trade secrets, trademarks, or any license or other proprietary interests and rights.

For OpenVMS VAX, the only RTL components that may be redistributed are the DECC$CRTL.OLB object library and the AACRT060.A saveset.

Redistribution of DECC$CRTL.OLB is required only by those applications that need to be linked during or after installation on an end user target system. When the library remains on the target system the library must reside in a product-specific location on the target system and not in SYS$LIBRARY. The contents of this object library cannot be inserted into the STARLET library.

For OpenVMS VAX Versions 5.5-2 the Compaq C++ VAX kit includes a separately packaged saveset that contains additional or modified run-time library components needed to execute programs developed with the Compaq C++ compiler and class libraries. Revisions to the run-time components are shipped with the OpenVMS operating system rather than the Compaq C++ compiler, and the components in this special Compaq C++ saveset, or more recent replacements, are included with OpenVMS VAX Version 6.1 or later.

# HARDWARE REQUIREMENTS

Processors Supported:

Any VAX system that is capable of running OpenVMS VAX Version 5.5-2 to Version 7.2. Refer to the OpenVMS Software Product Description (SPD 25.01.xx) for details.

Disk Space Requirements (Block Cluster Size = 1)

| Compaq C++ for OpenVMS VAX
Disk space required for Run-Time Kit installation: | 15,000 blocks (7.5 MB)
Disk space required for use (permanent): | 5,000 blocks (2.5 MB)
Disk space required for Debug kit installation: | 22,000 blocks (11 MB)
Disk space required for use (permanent): | 1,000 blocks (0.5 MB)
Disk space required for compiler kit installation: | 52,000 blocks (25.5 MB)
Disk space required for use (permanent): | 22,00 blocks (10.5 MB)

These counts refer to the disk space required on the system disk. The sizes are approximate; actual sizes may vary depending on the user's system environment, configuration, and software options. The Debug kit saveset installation is not used on OpenVMS VAX Version 6.0 systems, and the Run-Time Kit saveset installation uses greatly reduced space on OpenVMS VAX Version 6.0 systems.

# SOFTWARE REQUIREMENTS

- Compaq C++ for OpenVMS VAX requires OpenVMS VAX Version 5.5-2 to Version 7.2-1.
- The graphic user interface (GUI) for the debugger shipped with the Compaq C++ kit requires Motif Version 1.2-4 or higher.
