I is an matlab like interpreter for numerical calculations. Just like the python interpreter it can interpret command from a shell. The user types a command, which is processed by the interpreter. After processing, and possibly output of the result, a prompt is presented and the user can enter a new command. > > 1) by the user.

My first ideas were about communicating with pipes. After some reading I decided to look for something else, since I need two-way communication. When pipes are used, 'deadlocks' may occur: situations where both programs are waiting for input from the other site. > Apart from that I must admit I still don't know what you mean.

I want to make a graphical shell for octave, which allows the user to use it as if he was using it in its normal environment. Additionally I want my application to be able to communicate with octave without the user noticing. This is necessary for adding additional functionality over just a simple graphical shell. Hope I finally managed to make clear what I intend.
