defined clear_screen().  So it looks for the internal procedure with that
name, and does what is expected.  In order for oldclear_screen() to see the
user's clear_screen(), it would have to be called with
call_proc/routine_id.  This kind of method is useful for overriding built-
in Euphoria functions/procedures.  There's a lot more information about
this in the documentation, especially relating to compare and sort.

Ahhh! (light bulb turns on), thanks for clearing that up for me.  I guess
I'm too used to working with Windows (& win32lib) where routine_id is
frequently used (and clear_screen is usually never used).
