OpenVMS / VMS Programming Reference Manuals

(the VMS manuals are at the end of this page)

Sector7 have for the past 30+ years, written VMS functional equivalent libraries, and layered products that allow VMS / openVMS programs to run without manual change on Linux .

the Sector7 toolset allows you to maintain 1 code base on VMS and when ready "press a button" to convert, link and run your migrated / ported / rehosted application on Linux..

We have language translators to automatically convert VMS extended syntax to ANSI Syntax or to C/C++ (if no ANSI product available).

OpenVMS / VMS Programming Refefrence manuals


Sector7 noticed recently when looking for BLISS and PL/I manuals that the VMS manuals are becomming harder to find on the web.

we decided to collect new and old openVMS Manuals in one place and organize them for VMS Programming and Programmers. These are excellent manuals - but - indexed disjointly.

We hope this helps. You should always check with VSI, Oracle and their manual reference list: http://www.vmssoftware.com/documents & https://docs.oracle.com
