Tiziana,
I made some changes to the gribtonc source, now it appears that the
variables are being written. It kind of hard to tell because some of the
variables values are missing and or have very little data. I did get the
above ftp file to use as a test case. I made new tar.Z file that's
located in the ftp dir pub/decoders it's called decoders-2.3.9.tar.Z
Let me know if this solves your problems.
