Users can enter DCL commands at a terminal or include them in command procedures. These command proce- dures can be run interactively or submitted to a batch queue for later processing. Information about DCL and OpenVMS utilities is available on line through the Open- VMS Help system.

For users who are familiar with the UNIX shell and util- ities, an open source port of GNV is available. GNV implements a UNIX environment on OpenVMS and includes an Implementation of the UNIX shell BASH (Bourne Again Shell) and many UNIX-shell utilities.

The following tools and utilities are integrated into the OpenVMS operating system.

Text Processing

The Extensible Versatile Editor (EVE) is the default ed- itor for OpenVMS. EVE allows users to insert, change, and delete text quickly. EVE is a full-screen editor that allows users to scroll through text on a terminal screen. EVE provides an EDT-style keypad, allowing EDT users to move easily to EVE.

Mail Utility

The Mail utility allows users to send messages to any other user on the system. Multinode operation is avail- able if a DECnet or TCP/IP product is installed and li- censed on each participating node on the network.

Command-Level Programming

Command-level programming allows users to create special files, called command procedures, that contain a series of DCL commands. When users execute a com- mand procedure, the system processes the commands in the command procedure consecutively.

User Environment Tailoring

Users can customize the computing environment with login command procedures, shorthand commands, binding of commands to function keys, and command recall and editing.

PROGRAM DEVELOPMENT ENVIRONMENT

OpenVMS includes a comprehensive set of tools for de- veloping programs, including: run-time libraries (RTLs), a linker, a librarian, and a symbolic debugger.

The following tools are available to the OpenVMS pro- grammer.

Java™ SE Development Kit

The Java Platform, Standard Edition Development Kit (JDK) provides a development and deployment envi- ronment for Java applications on OpenVMS Alpha and OpenVMS for Integrity servers, including a set of basic development tools and a rich set of class libraries.

Language and Run-Time Library Support

OpenVMS includes several RTLs that provide:

•String manipulation

•Parallel processing support

•I/O routines

•I/O conversion

•Terminal-independent screen handling

•Date and time formatting routines

•Highly accurate mathematical functions

•Signaling and condition handling

•Other general-purpose functions

With OpenVMS Alpha, these routines can be called from programs written in such languages as MACRO- 32, MACRO-64, Ada, BASIC, C, C++, COBOL, Fortran, Pascal, and PL/I.

With OpenVMS for Integrity servers, these routines can be called from programs written in such languages as MACRO-32, BASIC, C, C++, COBOL, Fortran, and Pas- cal.

Also included in OpenVMS are language-support li- braries. While each language is different, all provide support for sequential file I/O, and most support direct and indexed file I/O. Language RTLs also provide sup- port for I/O formatting, error handling, and in Fortran, the ability to read unformatted files that contain data from other vendors.

RTLs are provided to support translated images created from user-mode images built on OpenVMS Alpha Ver- sion 6.1 through Version 7.3-2.

Calling Standard

Many HP languages adhere to the common calling stan- dard. This means that routines written in any of these languages can directly call routines written in any other language. Development of applications using multiple languages is simple and straightforward.

All user-accessible routines in the RTLs follow the appropriate platform calling standard and condition- handling conventions, and most are contained within shareable images.

OpenVMS I64 Operating Systems specifications

HP OpenVMS I64 is a robust operating system originally developed by Digital Equipment Corporation and later acquired by Hewlett-Packard. It stands for "Open Virtual Memory System" and is designed to run on Intel Itanium (I64) architecture, offering high reliability and performance for mission-critical applications.

One of the defining features of OpenVMS is its focus on availability and fault tolerance. It supports clustering, allowing multiple nodes to function together as a single system. This feature ensures that if one node fails, others can continue processing, minimizing downtime. Furthermore, OpenVMS employs a sophisticated method of process management, enabling the efficient handling of multiple tasks and processes simultaneously.

Security is a paramount characteristic of OpenVMS. The system implements a multi-layered security architecture, encompassing user authentication, access controls, and logging features that protect against unauthorized access. It also offers role-based access control, which streamlines permissions and bolsters overall system security.

OpenVMS is compatible with various programming languages and development tools, which makes it a versatile choice for developers. It supports languages like C, C++, COBOL, and Pascal, as well as development environments that facilitate the creation of sophisticated applications. Its comprehensive suite of development and debugging tools enhances productivity and ease of use for software engineers.

Another notable feature is its support for legacy applications. OpenVMS provides compatibility with older systems, allowing organizations to modernize their infrastructure without losing valuable investments in legacy code. This backward compatibility is vital for enterprises that require long-term system integrity and data consistency.

The operating system also features an advanced file system known as the Virtual Memory System (VMS) file system, which supports a variety of file types and efficient data management. The system is designed for high-performance I/O operations, which is crucial for applications that require quick data access and processing.

In terms of networking, OpenVMS supports a range of communication protocols, making it suitable for integration into complex networked environments. Its TCP/IP stack enables seamless connectivity with other platforms, facilitating collaboration in mixed environments.
