Don't fix it. Just add new words that add the offsets for the current actual
visible position. (Saying this not looking at any code). Something like 0 0
SETVIS-XY. Set clipping region or something in them.

Subject: [sftalk] TTY question

Hi Everybody,

The current functionality of the TTY window with regard to GET-XY and
SET-XY is that the entire window is part of that addressing scheme.
Specifically, if you have 100 lines scrolled off of the screen, and
execute "0 0 SET-XY" the cursor will be repositioned at the very top
of the buffer, not at the top of the visible screen.

I consider this broken; I think that "0 0 SET-XY" should reposition
the cursor to the top of the visible window.

The question here is: Does anyone depend on this behavior enough to
warrant NOT fixing it?

Thanks,
rick
