I think that not clearing previous output is a known limitation or bug
of the ":echo" command. To clear the output, you can (untested) start
your echo by a carriage-return, e.g. with
:echo "\n" . Hi_get_info()

THE LESSER-KNOWN PROGRAMMING LANGUAGES #2: RENE
Named after the famous French philosopher and mathematician Rene
DesCartes, RENE is a language used for artificial intelligence. The
language is being developed at the Chicago Center of Machine Politics
and Programming under a grant from the Jane Byrne Victory Fund. A
spokesman described the language as "Just as great as dis [sic] city of
ours."
The center is very pleased with progress to date. They say they have
almost succeeded in getting a VAX to think. However, sources inside the
organization say that each time the machine fails to think it ceases to
exist.
