Math ScriptConsole

Math ScriptConsole (MSC) lets you do mathematical calculations using scripts and commands in a console-based multiple-window interface.

You can either run single commands interactively or run a batch of commands from a script file. It's an ideal replacement for windows calculator which is too simple for scientists and engineers.

Math ScriptConsole is under the power and flexibility of Microsoft VBScript engine. It includes extra functions and libraries specifically designed for scientists and engineers.
What's more, it's very easy to add your own functions and create your own libraries.
