Can any kind soul tell me how to get vn working?

[A D Domaratius]

I missed the posting of vn when it was on the net.   Would someone
please post the program again.  I know it is lengthly but I would
appreaciate it.  By the way, is it in GNU UNIX(TM).  My computor is
on System V release 2.  If the vn is intended for GNU then it won't
work here I suspect.  Can it be modified? If so, how.

Thank you,
