Upon the date 11:00 PM 9/21/99 -0400, Allison J Parent said something like:

Sure would be a good source. But also you can subscribe to one of the
several Heath-related lists out there and get help and a manual from some
of us there (I don't have any Heath scope mans myself). I subscibe to one
which has been a good resource of info for me. Here's the tag lines the
Heath Listserver attaches to each msg (a la the ones ClassicCmp has in the
header most of us see):

>Sponsored by the City of Tempe
>
>Listserver Submissions: heath_at_listserv.tempe.gov
>Listserver Subscription: listserv_at_listserv.tempe.gov - "subscribe heath
'name' 'call'"
>Listserver Unsubscribe: listserv_at_listserv.tempe.gov - -"signoff heath"
>

Allison's and Tony's last messages are zeroing-in on what my thinking is as
to your problem(s). Listen to them.

Good luck with it.

Regards, Chris
