Public Domain version of: yes(1)

[Silver]

Hi everybody!  Since we're so intent on continuing this discussion,
and I need a break from the *real* stuff for a minute, I decided to
write my own yes!  I phoned my folks, and got my mom to work on her
version in Lotus.  My dad doesn't know any computer languages, but at
least he can type for my mom...  Rex (our dog) knows Logo, and is
de-flea-ing his version as I tap.  I've posted calls for versions to
all the networks and PA-Unix boxes to which I have easy access; I
volunteer to painfully post each one seperately.

This satisfies my sun's man page of yes.
