UNIX System V/386 Release 4 gets X/Open official approval
MORRISTOWN, N.J. -- JULY 16, 1990 --UNIX System Laboratories, Inc., today said that UNIX(R) System V/386 Release 4 has received an X/Open brand, signifying that the operating system source code has passed X/Open tests for conformance with the latest open systems industry standards.
UNIX System V/386 Release 4 is a source code `reference port' for computers based on the Intel 386 and i486 microprocessors. UNIX System V Release 4 source code for the AT&T 3B2 computer received the X/Open brand on June 5, 1990.
"Compliance with X/Open's Portability Guide is crucial to the commercial acceptance of Open Systems. We're proud that these versions of UNIX System V Release 4 source code have been proven worthy of the X/Open brand," said Mike DeFazio, vice president, UNIX System V Software at UNIX System Laboratories, Inc. (USL), formerly AT&T's UNIX Software Operation.
"We will continue to build products that comply with X/Open portability standards and to submit those products for the X/Open brand," DeFazio said. "We hope our customers do the same and that end users increasingly require compliance with X/Open standards in their procurements."
Several other USL products also received X/Open "Component" brands. Among them were the XWIN(TM) Graphical Windowing System, USL's implementation of MIT's X Window System(TM); the company's C programming language offerings; and UNIX System V Release 4 commands and utilities, internationalized system calls, terminal interface routines, and interprocess communication (IPC) routines.
In order to receive an X/Open brand, UNIX System V Release 4 source code had to pass X/Open's XPG3 Verification Suite, which subjects a product to a minimum of 5,500 tests against agreed upon Open Systems standards.
According to X/Open, UNIX System V Release 4 is the only souce code product that has received an XPG3 brand. Binary UNIX System V Release 4 products from AT&T Computer Systems, ICL and Olivetti have received X/Open brands. Many products based on earlier versions of UNIX System V have also received X/Open brands.
UNIX System Laboratories, Inc., a subsidiary of AT&T, was formerly known as AT&T's UNIX Software Operation. USL, with the guidance of UNIX International Inc., develops and markets UNIX System V and related systems software in source code form to computer hardware and system software vendors worldwide.
