Kernel Source Archive: 4DOS

4DOS was a replacement for command.com on MS-DOS and compatible systems. It enchanced the built-in command interpreter with a number of additional features, including aliasing and command-line editing support without requiring an additional utility, colour-coded directory listings, support for REXX in batch files, and many more.

In 2006, 4DOS 7.50.1 was released as open source under a modified MIT license, limiting the distribution of compiled versions to those for use on the FreeDOS.

4DOS can be found in the Kernel Source Archive Subversion repository at /kernelsource/4DOS.
