FoxPro 2.6 for SCO Unix and Xenix, due out next month and said to incorporate the same features and functionality as the MS-DOS version, fulfills a promise made by Fox Software Inc executives back in 1989 when they were still in charge of an independent company, then based in Perrysburg, Ohio, to bring FoxBase+ in line with FoxPro, before the company sold FoxPro to Microsoft Corp in 1992. Although Microsoft says that it will continue support for the current product line, with the five-year-old promise fulfilled, Unix implementations of the next FoxPro 3.0 release cannot be guaranteed.
