IBM PC DOS 2000 is the year 2000 ready solution that includes PC DOS 7.0 with enhanced support for year 2000 and Eurocurrency. It is certified by the Information Technology Association of America (ITAA). As a year 2000 ready solution, it's the way to standardize on one Year 2000 ready version of DOS because it easily upgrades from older DOS versions (3.3 or later). It contains software updates for older systems that incorrectly handle the century rollover. The new Eurocurrency symbol is supported. PC DOS 2000 includes full-function DOS and Windows utilities of PC DOS 7.0; more memory, performance, and features that provide optimum compatibility with DOS and Windows applications.
