I have an old badly-written Fortran program (I wrote it for a Vax, but it
still compiles and runs in g95 - isn't Fortran wonderful?) that takes
Arnott & Dover's polar coordinates and converts them to a helix of any
required length* in PDB (or Diamond!) format.

Wow, that is an old program!
For everyone under the ago of 60 reading this list, Diamond
format was the very first PDB format, used for the first 100
or so entries that we had. It was based on the output format
of the Diamond real-space refinement program and each line was
132 characters long. Long lines were awkward, in some ways,
to handle on computers of that time so we designed what is
now known as PDB format. If you want to know more, you can
look at page 9 of the September 1974 PDB Newsletter (available
on the RCSB web site if you start at
http://www.rcsb.org/pdb/static.do?p=general_information/news_publications/newsletters/newsletter.html#pre1999)
for the format of coordinate records in the original format.
The reason that I know that there were about 100 entries
released in the original format is that I was the one who had
to convert them all into the new PDB format in 1976.
