Yes, I did copy the idl_grib.dlm and idl_grib.so files
under /usr/local/itt/idl/bin/bin.linux.x86 (running under linux)..
at first I also thought about these two files, but still didn't work.
One thing I learned is I really didn't need the resolve_routine
commend (thx David).
Actually I also copied all necessary grib scripts under the working
directory.
Library path looks fine. I copied the necessary .dlm & .so files.. I
don't
understand why I can read the files under v6.3 but still not under
v7.0..
Thanks all,
Ray
