Computer Associates Panvalet (also known as CA-Panvalet) is a revision control and source code management system originally developed by Pansophic Systems for mainframe computers [1] such as the IBM System z and IBM System/370 running the z/OS and z/VSE operating systems. [2]

Overview

Panvalet can be used to manage program source code, JCL, Macros/commands for utilities such as Easytrieve [3] and object module files.

History

Panvalet was developed by Pansophic Systems in 1969 as a program to store and manage computer program source code on direct-access storage devices. [4] 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. [4] 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. [4]

Pansophic began selling the program in 1970 at a price of $2,880 per copy. It was immediately successful. [4]

In 1978, it was reported that Panvalet, at the time a product of Pansophic Systems, Inc, [5] was in use at over 3,000 sites. [6]

Throughout much of its existence, the main competitor to Panvalet was The Librarian product from Applied Data Research. [7] [6] [8] It had roughly the same number of installations as Panvalet. As recollected by Piscopo, "Panvalet and Librarian basically divided the program library market between the two of them.... Virtually everyone ended up with one or the other of the products." [4]

Computer Associates acquired Panvalet in 1991 when it purchased Pansophic Systems for $390M. [9] Broadcom acquired Panvalet in 2018 when it purchased Computer Associates. [10]

In computer programming, assembly language, often referred to simply as assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions. Assembly language usually has one statement per machine instruction (1:1), but constants, comments, assembler directives, symbolic labels of, e.g., memory locations, registers, and macros are generally also supported.

The history of software configuration management (SCM) in computing can be traced back as early as the 1950s, when CM, originally for hardware development and production control, was being applied to software development. The first software configuration management was most likely done manually. Eventually, software tools were written to manage software changes. History records tend to be based on tools and companies, and lend concepts to a secondary plane.

A source-to-source translator, source-to-source compiler, transcompiler, or transpiler is a type of translator that takes the source code of a program written in a programming language as its input and produces an equivalent source code in the same or a different programming language. A source-to-source translator converts between programming languages that operate at approximately the same level of abstraction, while a traditional compiler translates from a higher level programming language to a lower level programming language. For example, a source-to-source translator may perform a translation of a program from Python to JavaScript, while a traditional compiler translates from a language like C to assembler or Java to bytecode. An automatic parallelizing compiler will frequently take in a high level language program as an input and then transform the code and annotate it with parallel code annotations or language constructs.
