Text mode rendering
The text user interface (TUI) has been designed for character-based terminals. This mode can be used to run your application on a text terminal hardware or in a terminal emulator.
In order to run a Genero program on text mode, set the FGLGUI environment variable to 0 (zero).
In TUI mode, the application windows/forms will display within the current console/terminal window as shown.

On UNIX™ platforms, you need to configure your terminal capabilities with the TERM, TERMINFO or TERMCAP environment variables.
