Any computer needs a text editor. Here we are.

We can write in the screen, we can open a store file.

Edit it and store it with the help of the Save button. 

The CLS button clears the screen. If we save the file and the screen is empty the program deletes the file.

The Com button reads the file line by line, and executes in the math engine these lines, adding the output to the file out.txt.

The Dic button shows the Eigenmath most used functions.
