If you would be so kind as to send me your user id number, I will
send you the Type716 documentation in a separate email. Please send
the user id number directly and do not reply to the entire list! The
number can be found by opening your user17.id file using a test
editor. The number should have the form 17-Xyyyy where X is a letter
and yyyy is a four-digit number. Please also send the project (*.tpf
file) that results in effectivenesses greater than 1 so I can have a
look at that as well.<br>
Kind regards,<br>
David<br>
