On this page DOS programs for which there are still no replacements in Windows or OS/2-eCS. You have to think in terms of convenience, ease, easy exchange of data etc. DOS is no longer supported in Windows. Most DOS programs will work if it were a part of OS/2. With the emulator DOSBox you can run so called "large model" DOS programs. This kind of DOS program claims the whole PC for themselves. The Psion 3x emulator is such a program. A nice thing is that only with OS/2-eCS you can copy, cut and paste text in this kind of programs while those programs don't know anything about these features.
