4DOS
4DOS is a command line interpreter of the company JP software that replaces the supplied, poorer functional interpreter COMMAND.COM in MS - DOS-compatible DOS operating systems. Originally distributed as shareware, 4DOS version was released by 7:50 under a modified MIT license as open source program without support from the manufacturer. From 2006 to 2009 this software from Lachezar Georgiev ( Bulgarian Лъчезар Георгиев, transliteration Luchezar Georgiev ) was developed.
Compatible developments
Largely compatible developments for other operating systems are 4OS2 (now also open source) for OS / 2, and 4NT and Take Command for Windows NT ( proprietary), which were also developed by JP Software. Only Take Command is still sold by JP Software.
The Norton Utilities included NDOS, one based on version 4 license version of 4DOS. This had been fully localized for the German market.
