The name of the OpenVMS AXP operating system has been changed to the OpenVMS Alpha operating system. Any references to OpenVMS AXP or AXP are synonymous with OpenVMS Alpha or Alpha.
VMScluster systems are now referred to as OpenVMS Cluster systems. Unless otherwise specified, references to OpenVMS Clusters or clusters in this manual are synonymous with VMSclusters.
In this manual, every use of DECwindows and DECwindows Motif refers to DECwindows Motif for OpenVMS software.
The following conventions are also used in this manual:
| Ctrl/ x | A sequence such as Ctrl/ x indicates that you must hold down the key labeled Ctrl while you press another key or a pointing device button. |
|
PF1
x or
GOLD x |
A sequence such as PF1
x or GOLD
x indicates that you must first press and release the key
labeled PF1 or GOLD and then press and release another key or a
pointing device button.
GOLD key sequences can also have a slash (/), dash (--), or underscore (_) as a delimiter in EVE commands. |
| [Return] | In examples, a key name enclosed in a box indicates that you press a key on the keyboard. (In text, a key name is not enclosed in a box.) |
| ... |
Horizontal ellipsis points in examples indicate one of the following
possibilities:
|
|
.
. . |
Vertical ellipsis points indicate the omission of items from a code example or command format; the items are omitted because they are not important to the topic being discussed. |
| ( ) | In command format descriptions, parentheses indicate that, if you choose more than one option, you must enclose the choices in parentheses. |
| [ ] | In command format descriptions, brackets indicate optional elements. You can choose one, none, or all of the options. (Brackets are not optional, however, in the syntax of a directory name in an OpenVMS file specification or in the syntax of a substring specification in an assignment statement.) |
| { } | In command format descriptions, braces indicate a required choice of options; you must choose one of the options listed. |
| text style |
This text style represents the introduction of a new term or the name
of an argument, an attribute, or a reason.
This style is also used to show user input in Bookreader versions of the manual. |
| italic text | Italic text indicates important information, complete titles of manuals, or variables. Variables include information that varies in system messages (Internal error number), in command lines (/PRODUCER= name), and in command parameters in text (where device-name contains up to five alphanumeric characters). |
| UPPERCASE TEXT | Uppercase text indicates a command, the name of a routine, the name of a file, or the abbreviation for a system privilege. |
| Monospace type |
Monospace type indicates code examples and interactive screen displays.
In the C programming language, monospace type in text identifies the following elements: keywords, the names of independently compiled external functions and files, syntax summaries, and references to variables or identifiers introduced in an example. |
| - | A hyphen in code examples indicates that additional arguments to the request are provided on the line that follows. |

The main features of OpenVMS Version 7.1 provide improved OpenVMS Cluster performance, options for improving the performance of very large database applications, easier system management, and the ability to easily connect OpenVMS systems to the Internet.
Table 1-1 summarizes each feature provided by OpenVMS Alpha and OpenVMS VAX Version 7.1 and presents these features according to their functional component (general user, system management, or programming).
| General User Features | |
|---|---|
| DCL commands |
Two new DCL commands have been added:
|
| OpenVMS freeware | The OpenVMS Freeware CD-ROM contains free software tools and utilities that aid OpenVMS software development and system management. |
| Internet support | The OpenVMS Internet Product Suite offers a convenient and comprehensive portfolio of Digital and third-party internet products, tools, and utilities you can use to set up and maintain intranet or Internet sites. |

| Dump file features |
OpenVMS Version 7.1 includes the following new dump file features:
|
| External authentication support | Allows users to log in (or sign on) to an OpenVMS system at the OpenVMS login prompts with user IDs and passwords from an external authenticator (such as LAN Manager). |
| Fast Ethernet LANs (Alpha systems only) | OpenVMS Alpha Version 7.1 supports Fast Ethernet LANs that raise the data transmission rates from 10Mb/s to 100Mb/s. |
| High SCSI IDs (Alpha systems only) | OpenVMS Alpha Version 7.1 supports up to 16 SCSI devices per wide SCSI bus. This enables devices that support the wide SCSI bus option to use existing hardware more fully for device identification. |

This chapter provides new features information for all users of the OpenVMS operating system.
This section describes the new DCL commands for OpenVMS Version 7.1.
OpenVMS Version 7.1 introduces some popular UNIX command shell processing functions. With the PIPE command, you can quickly create complex command processing statements that combine the following operations in a single DCL command:
For example, the following PIPE command runs a test program, sorts the results, and compares those results to a benchmark file. This single command statement simplifies processing and eliminates intermediate files.
$ PIPE RUN TEST.EXE | SORT/SPECIFICATION=TEST.SRT SYS$INPUT SYS$OUTPUT - | DIFF SYS$INPUT TEST.BENCHMARK
This style of command processing also supports the development and use of Internet software, which often expects some form of pipeline command parsing to be present on both host and target systems.
For a more detailed description of this command, see the OpenVMS DCL Dictionary: N--Z.
The DCL command PPPD invokes the Point-to-Point Protocol utility, new with OpenVMS Alpha Version 7.1. This utility enables you to set up both permanent and temporary serial network connections between an OpenVMS Alpha workstation and a specific local or remote host. However, the host must support the Point-to-Point Protocol (PPP) internet communication standard (STD 51) established by the Internet Architecture Board (IAB).
For more detailed information about the PPPD command, see the OpenVMS DCL Dictionary: N--Z. For a description of the Point-to-Point Protocol utility, see Section 2.4.
OpenVMS Engineering is offering the OpenVMS Freeware Version 3.0 CD-ROM with the OpenVMS Version 7.1 distribution kit. It contains free software that runs on OpenVMS Version 6.0 or later and provides you with easy access to public domain software and free internal Digital tools that facilitate software development and system management.
The OpenVMS Freeware CD-ROM features the following:
