implements a text editor for interactive programming

Description

This is a very powerful keyboard input editor. With it you can interactively write texts line by line over several lines. You can move the cursor within one line or over several lines.
The function returns its necessary input parameters as output parameters, making it possible to restart the editor over and over again.
The function is used within the SGofCPLcommandui to analyze and draw the drawing chain after each space character.
