I appreciate your comments.  I realize ^L clears the
screen.  My app normally runs from within emacs and I
sometimes capture hundreds of thousands of lines of
debugging output in a single emacs buffer.  This can be
navigated thru using a whole collection of custom elisp
functions.  Emacs is remarkable tolerant about these
large files.  Any how, that's my use case.

The ^L should work better for interactive sessions,
as you suggest.

thanks for your reply
