Ok I think I have it far enough now to call it beta.
to summarise:
-every character of
Windows-1252(ansi) is defined and may (if there is no key for it) be written per entering his hex-value while pressing ENTER.
-exeption are control characters, only \t \r \n are defined. (I'm not sure if the others are needed actually)
-you can store up to 900 characters. (if you write more than fits on the screen it's going to look as if he would overwrite the first characters but that doesn't really happen)
-speaking of storing, you can either store it temporary or in a file called "nwriter.txt.tns".
-this file, you can also write on your Pc. Then you have to save it in the same directory as nwriter.tns (hasn't any more to be the root directory)
-by pressing CAT (the key with the book on it) you can invert the color of the screen.
If you write a .txt file on your Pc make sure that your text editor uses \r\n for "enter". (the ones on windows do it "most" of the time)
Tomorrow I will see if my screen recorder still works but for today I'm to tired.
