Use TheDraw, and draw the custom screen. Then turn on animation mode,
and draw the prompt where you want it, and before you save the file,
press the spacebar where you want the user's input to go. I recommend saving the file with the ClearScreen option (you'll see it when you
save.)
There is a better way to do this with mystic. Draw the screen, and then
create the cursor placement with built-in Mystic display codes (see Mystic
BBS wiki).
Doing ansimation has drawbacks, not least of which is being able to edit the ansi after the fact. I'd strongly recommend against this method.
