Take Command Console

Take Command Console (TCC), formerly known as 4DOS for Windows NT (4NT), is a command line interpreter by JP Software, designed as a substitute for the default command interpreter in Microsoft Windows, CMD.EXE.

History

TCC is based on the earlier 4DOS command shell for DOS, and 4OS/2 for OS/2.

The NDOS interpreter and batch file extensions included with several Norton Utilities implementations prior to 2000 is a lightly modified and extended 4DOS interpreter.

Beginning with version 12 of 4NT, support for Windows 95, 98, ME, NT and 2000 were removed. Beginning with version 16 of TCC, support for Windows XP was removed, although it might still run in XP. 4NT was renamed to Take Command Console as part of JP Software's Take Command version 9.

Features

TCC provides a rich set of command line and batch programming capabilities. 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), and the scripting engine version of Object REXX to provide greater access to the operating system.

Norman four notrump

Norman four notrump (also Norman) is a slam bidding convention in the partnership card game contract bridge designed to help the partnership choose among the five-, six-, and seven-levels for the final contract. Norman four notrump is an alternative to the Blackwood convention family.

Used when the contract level can be better determined by knowing the numbers of aces and kings that are "missing" in the partnership's two hands, the convention is initiated by a bid of 4NT to ask that partner provide information about his ace and king holdings. The response is coded to enable inference about the precise numbers of aces and kings in the replying hand.

The Norman scale, where an ace counts as one control and a king as half a control, is the basis of the following responses to the 4NT asking bid:

Norman 4NT was a component of the Vienna System developed in the 1930s and the sixth edition of The Official Encyclopedia of Bridge of 2001 noted that it "once was popular in England, where it is credited to Norman de Villiers Hart and Sir Norman Bennet."
