Labels would be created using "echo" (with embedded ANSI sequences as 
necessary for cursor movement etc).

Since menus are not automatically cleared from the screen, you could 
also plausibly leave the menu in place and create an edit box towards 
the bottom of the screen, or replace the current menu row with an edit box.

It could, but I try to avoid doing that.
