Panvalet


Panvalet® is a revision control and source code management system for mainframe computers such as the IBM System z and IBM System/370 running the z/OS and z/VSE operating systems. Unlike open-source solutions such as CVS, SVN or Mercurial, Panvalet is a closed source, proprietary system for versioning and control of source code such as Microsoft Visual SourceSafe on personal computers.
CA-PAN/LCM is a similar product for PCs.

Overview

Panvalet uses a client-server model where users check-out files to change and check them back into the repository when finished. It can be used to manage program source code, JCL, Macros/commands for utilities such as Easytrieve and object module files.
It supports granular access controls including check-in and check-out by specific mainframe user IDs.

History

In 1978, it was reported that Panvalet, at the time a product of Pansophic Systems, Inc, was in use at over 3,000 sites.
Earnings reports for Pansophic were tracked by The New York Times.
