I agree - the console window should be thought of as a single page.
Sometimes it's larger than what can be displayed, hence the scroll bars.
IMO, the vertical behavior should match the horizontal behavior.

Either way though, it won't affect me.

Rick,

After some 'little experiments', my suggestion is to give PAGE the same
functionality as the 'clear page' menu button: remove all history. This
makes the get-xy, at-xy coordinates always physically 0,0 based.

As Elizabeth said, it's important for the kind of fast screen updating
we do that the origin DOESN'T CHANGE when the current line 0 is scrolled
off the screen. (We only rewrite changed table entries.) This means that
some updates may not be seen until the screen is scrolled back, but they
are in the right place.

The downside is that one must turn logging on prior to thinking you
might want to save the previous stuff when you use PAGE. (Maybe the
default should be LOGGING ON with a generic console.log file in the ???
directory?) It would require clarifying documentation (which says
nothing about it now).

My 2 cents,
John
