[SOLVED] simple cursor-addressable command?

Hi Everyone

I always wondered how Lynx and VI could take input the way they do. Now I know it's because they are using the cursor-addressable feature of the terminal they are runnning it, or in other words they are moving the cursor to different places on the screen.

These projects have large code bases though. Is there an example of a command that uses this but is small? I just want to study how it works.

Thanks for reading-Patrick

curses is the system of terminal independent cursor control. libncurses5 (new curses v5) is what Linux has used since the beginning.

Python has a nice wrapper around libncurses5 and good example code.
