French flagship computer manufacturer Bull SA has claimed first place in the line to offer X/Open branded Unix systems. Bull has become the first manufacturer to gain a licence from X/Open allowing it to use the brandmark on the Bull DPX 2000 system. To win the licence, the machine had to pass the 3,745 tests for conformance to X/Open’s Portability Guide 2 set by Unisoft Corp’s verification suite. Systems are required to pass the 1,578 operating system and 1,292 C language tests at a single pass without showing errors. The Bull system will now run any software compliant with X/Open’s second Portability Guide, including those listed in the recently published X/Open software catalogue, around 240 products.
