4NT

4NT is a command line interpreter by JP Software, designed as a substitute for the default command interpreter in Microsoft Windows. 4NT is based on the earlier 4DOS command shell for DOS, and 4OS/2 for OS/2 and in fact older versions were named 4DOS for the Windows NT Operating System.

Beginning with version 7, support for Windows 95, 98, and ME were removed.

4NT was renamed to Take Command Console, as part of the JP Software's Take Command version 9, a version of 4NT which has many more features and more extensive GUI integration. The current version of TCC and therefore the underlying 4NT scripting language variant is 9.0.

4NT provides a rich set of both command line and batch programming capabilities. Unlike NT-based command line interpreter, it does not directly accept Windows Script Host commands. It can work in conjunction with other scripting languages, such as REXX, Ruby and Perl, or Windows Scripting languages, in the form of Active Scripting engines such as VBScript and JScript as well as PerlScript (via ActivePerl), TclScript (via ActiveTcl), PythonScript (via ActivePython), the scripting engine version of Object REXX to provide greater access to the operating system. 4NT is used by data center operations, tech support staff and programmers, as well as power users.
