Take Command and Take Command Console are a Windows GUI command-line toolkit, and Windows console command shell, respectively, from JP Software. They provide an extremely powerful command-line facility that can completely replace the Windows CMD shell, while adding literally hundreds of new features, commands, variables and functions. They also extend the Windows batch file facility to an incredible degree, while remaining completely compatible. Take Command Console, or TCC, was formerly known as 4NT. I have been using this software since 1992 on MS-DOS, when it was known as 4DOS.
Take Command Lexer is, as the name implies, a lexer for Textadept, for TC/TCC batch files.
