Chapter 8: The OpenVMS HELP Facility

OpenVMS comes equipped with an extensive online HELP facility that you may use to learn what commands are available, what they do, and how to use them.

Note 

Third-party software that introduces new commands onto an OpenVMS system may or may not update the OpenVMS HELP database to include descriptions of its own commands.

Learning How To Use HELP

To learn about the HELP facility, enter HELP INSTRUCTIONS at the DCL prompt. A short tutorial appears describing how to find information about DCL commands.
