Clint,

I have an updated shape.tar.gz file in
http://www.unidata.ucar.edu/packages/gempak/contrib/shape.tar.gz

Don't know if it will have any more luch, but I did revamp some
of the code. The main thing to look at is the NDEX_SIZE definition
for the ndex[] array which is currently set to 600 parts of
the message. If this is a problem, the will write out a message.

See the README file inside. I removed the -g flag. That is the default format.
