Are you asking how to associate .BAT files with TCC? It's easy to do, but it may cause problems for you. .BAT files sometimes rely on peculiarities of Microsoft's shells, and may not work quite the same way in Take Command.
Instead, I'd suggest making a copy of your batch file with a .BTM extension. .BTM files are probably already associated with TCC. If not, you can run the file TCCBATCH.BTM (in your Take Command directory) to associate .BTM files, and optionally .BAT and .CMD files, with TCC.
