Compaq Software Product Description ___________________________________________________________________ PRODUCT NAME: Compaq Ada Version 3.5A for OpenVMS VAX Systems SPD 26.60.18 DESCRIPTION This Software Product Description includes the following two products: o Compaq Ada for OpenVMS VAX Systems o Compaq Ada Professional Development Option for OpenVMS VAX Systems Compaq Ada for OpenVMS VAX is the Compaq Computer Corporation imple- mentation of the full ANSI/MIL-STD-1815A-1983 Ada Language. As a re- sult of meeting the ANSI standard, Compaq Ada also conforms to the Fed- eral Information Processing Standard (FIPS-119). The Compaq Ada compiler runs on the OpenVMS operating system and generates optimized, shareable, and position-independent code. As a native mode OpenVMS language, Compaq Ada is integrated into the OpenVMS common language environment. All OpenVMS system services and utilities are available to programs written in Compaq Ada. Compaq Ada supports the OpenVMS Record Management Services (RMS) sequential, rel- ative, and indexed file organizations and associated access methods. Compaq Ada programs can invoke modules written in other OpenVMS languages. Additionally, programs written in other languages can invoke Compaq Ada modules. Ada is a powerful, general-purpose language that supports many modern programming practices. The language was designed as the result of a competition sponsored by the United States Department of Defense. The purpose of the competition was to define a language suitable for programming-embedded computer systems. Among the requirements for the June 2000 AE-EU91R-TE language are features that reduce software costs by increasing main- tainability, evolvability, reliability, and portability. Ada provides a modular structure for programs by allowing separate com- pilation of program units, as well as providing strong typing, tasking, exception handling, and other standard language features that must be supported across implementations. Ada provides a number of features from general systems to real-time applications. Ada Language Features o Strong Typing - An object (variable) of a given type may take on only those values that are appropriate to that type, and only cer- tain predefined operations may be performed on data of that type. Because type checking is done at compile time, strong typing en- sures that any errors associated with incorrect data types are detected at compile time. o Data Abstraction - Also known as information hiding, data abstrac- tion hides implementation details while providing users with mech- anisms for using the implementation. Abstraction allows users to focus on important characteristics while ignoring underlying de- tails. Ada provides various levels of abstraction through features such as private data types and packages. o Concurrent Processing - For many applications, it is important that a program be conceived of as a number of parallel, rather than serial activities. Most high-order languages provide little or no support for handling such parallel or concurrent activities. They rely on facilities of the host operating system. Ada uses tasks to allow parallel activities to be programmed directly within the language. o Separate Compilation - Ada's separate compilation feature allows a programmer to divide a large program into compilation units that may be compiled at different times. When a unit is compiled, the Ada program library manager records information about that unit and other related units. This feature is unlike separate compilation features in other languages where little information about separately compiled modules is maintained. 2 o Generic Definitions - A generic unit is a template from which specific instances can be made at compile time. In many cases, the logic of an algorithm or a set of operations is independent of the specific type of the values being manipulated. However, in a strongly typed language such as Ada, all types must be defined at compile time. Generic definitions let the user define a general algorithm or set of related operations and then create a specific instance of that algorithm or set of operations for each type to which the algorithm or operations must apply. o Exception Handling - In many operations, especially embedded computer systems, it is critical that a system be able to recover quickly and efficiently from error conditions. Ada provides the ability to raise and handle exceptions. It includes predefined exceptions and also permits the user to define exceptions. When an exception occurs in an Ada program, normal processing is abandoned and control passes to the exception handler. Compaq Ada Components and Special System-Related Features: o Ada compiler that fully conforms to ANSI/MIL-STD-1815A-1983. For details see the DEC Ada Language Reference Manual. o Ada program library manager that provides support for programming teams through: - Program libraries that can be shared by many programmers - A powerful search list model for program libraries. This per- mits the following: * The relationships among program libraries can be changed easily. * Individual programmers can establish different views of program library relationships. - Automatic recompilation of obsolete compilation units - The ability to share compiled Ada code either by reference or copy 3 o Strongly typed Compaq Ada bindings that provide interfaces for the following versions of X Window Systems[TM] and Motif[R] routines: - X Window System Version 11R4 and Motif Version 1.1.3 - X Window System Version 11R5 and Motif Version 1.2 o Implementation of AI-00866, which permits an 8-bit character set based on ISO standard 8859/1 (commonly known as Latin-1). o Availability of a portability command that causes a portability sum- mary report to be included with the compilation listing file. The report indicates the use of potentially nonportable features and constructs. o Support for the ISO Math Library packages GENERIC_PRIMITIVE_FUNCTIONS and GENERIC_ELEMENTARY_FUNCTIONS. o Debugging capability provided through the OpenVMS Debugger. High-level, fully symbolic debugging including support for debugging tasking programs, packages and mixed Compaq Ada and non-Ada code. o Integration with OpenVMS VAX operating system including: - Conformance to the OpenVMS VAX Calling Standard, which allows Ada code to call and be called by code written in other languages, as well as to call OpenVMS system services and the OpenVMS VAX Run-Time Library - The ability to call Open Record Management Services (RMS) routines directly - Full access to relative and indexed file capabilities - The ability to handle exceptions from non-Ada code and generate exceptions to be handled by non-Ada code - The ability to handle OpenVMS asynchronous system traps (ASTs) 4 - The ability to link with shared images and use shared global sections - The ability to share data with non-Ada code through global variables and psects (common blocks) o System-dependent facilities - Different systems vary in such char- acteristics as the size of storage units, memory size, and the smallest and largest integer values supported. Compaq Ada provides the predefined package SYSTEM to define system-related constants and to represent system-dependent information. o Compaq Ada provides representation clauses that allow the user to tailor the representation of data to suit a particular system. Compaq Ada provides: - Length clauses that specify the amount of storage associated with a type - Enumeration representation clauses that specify the internal codes for the literals of enumeration types - Record representation clauses that specify the layout of a record type, such as the order, position, and size of record components - Address clauses that specify required addresses in storage for objects, imported subprograms, or single entries o Compaq Ada provides a number of pragmas (compiler directives) that allow various system-related parameters to be set and changed and control mixed-language programming. o Comprehensive diagnostic messages with references to the DEC Ada Language Reference Manual. This feature is directed at helping the new Compaq Ada user. 5 Compaq Ada Professional Development Option for OpenVMS VAX Systems The Compaq Ada Professional Development Option is a separately licensed option that is available with Compaq Ada on OpenVMS VAX Systems. The Compaq Ada Professional Development Option includes the following ca- pabilities: o Smart Recompilation - This feature can significantly reduce the number of recompilations that are needed to rebuild a Compaq Ada program after some compilation units change. Smart recompilation enables the compiler to propagate changes quickly through a system, eliminating up to 100% of the usual recompilations. o Program Library File-Block Caching - This feature uses an in-memory cache of file blocks to minimize the actual amount of disk input- output that must be performed. As a result, the elapsed time for compilations is significantly reduced. o Multilevel Program Library Directory Structure - This feature pro- vides a more efficient program library directory structure to improve the performance of access to large program libraries. The Compaq Ada Professional Development Option is designed so that it is compatible with libraries that are created without the Compaq Ada Professional Development Option and libraries created with a previous version of Compaq Ada. Once a program library is created, Compaq Ada programmers do not need to change any of their development pro- cedures to benefit from the Compaq Ada Professional Development Option.
