Computer Associates Panvalet (also known as CA-Panvalet) is a revision control and source code management system for mainframe computers[1] such as the IBM System z and IBM System/370 running the z/OS and z/VSE operating systems.[2]
CA-PAN/LCM is a similar product for PCs.[1]
Panvalet uses a client-server model where users check-out files to change and check them back into the repository when finished.[3] It can be used to manage program source code, JCL, Macros/commands for utilities such as Easytrieve[4] and object module files.
It supports granular access controls including check-in and check-out by specific mainframe user IDs.[5]
Panvalet was developed by Pansophic Systems in 1969 as a program to store and manage computer program source code on direct-access storage devices.[6] Before Panvalet code was saved as paper punch cards, typically with 500 to 3,000 cards per program, often 1,000,000 or more per data center.[6] Cards were bulky, difficult to store and transport, difficult and costly to back up, and prone to catastrophic errors since one misplaced card could prevent a program from running correctly.[6]
Pansophic began selling the program in 1970 at a price of $2,880 per copy. It was immediately successful.[6]
In 1978, it was reported that Panvalet, at the time a product of Pansophic Systems, Inc,[7] was in use at over 3,000 sites.[8][9]
Earnings reports for Pansophic were tracked by The New York Times.[10][11][12][13]
Computer Associates acquired Panvalet in 1991 when it purchased Pansophic Systems for $390M.[14] Broadcom acquired Panvalet in 2018 when it purchased Computer Associates.[15]
