This manual is intended for all users of the HP OpenVMS operating system. It includes descriptions of all DIGITAL Command Language (DCL) commands and lexical functions. If a command has any restrictions or requires special privileges, they are noted in reference information for that command.
Readers of this manual should be familiar with the material covered in the OpenVMS User's Manual.
This manual contains detailed descriptions of each command and lexical function. The commands are listed in alphabetical order, with the command name appearing at the top of every page. The lexical functions are grouped under the heading Lexical Functions (after the JOB command description) and are listed alphabetically within that grouping; the lexical function name appears at the top of each page.
The hardcopy version of the HP OpenVMS DCL Dictionary is a two-part manual. The first volume contains commands beginning with the letters A to M (including the lexical functions); the second volume contains commands beginning with the letters N to Z.
Appendix A of this manual (in the second volume of the hardcopy manual) lists the obsolete DCL commands and the current services that replace them.
The commands that invoke language compilers and other OpenVMS optional software products are not included in this manual; they are included in the documentation provided with those products.
For an introduction to the OpenVMS operating system and for information on using DCL, see the OpenVMS User's Manual. This manual is especially recommended for novice users or users lacking experience with interactive computer systems.
The OpenVMS User's Manual provides an overview of DCL command language concepts and defines and illustrates good practices in constructing command procedures with DCL commands and lexical functions.
See the various utilities reference manuals for detailed information about utilities. These manuals describe the DCL commands that invoke the various utilities, describe any commands that you can enter while running a utility, and provide reference information. The HP OpenVMS DCL Dictionary provides only a brief description and format information for each utility.
