I think you may be confusing releases with RCS file versions,
but I'm not sure.
Here our RCS version history of the file NetcdfFile.java

So, the _file_ for RCS version in use on 1998/06/03
should have been 1.4. Perhaps you checked it in locally
and that changed the RCS header. That would lead to slight differences.
The 'patch' program should be able to deal with that. It will just
not change ("reject") the rcsid section. If you have trouble, I can send
the whole file.

The 'copyout()' method, documented in the multiarray.Accessor interface,
is most like the the C/FORTRAN get method you are used to. The result is
an instance of MultiArrayImpl, which has a 'toArray()' method to convert
it to a java language array.

I'm working on a MultiArray adapter class that takes a MultiArray of type
Character and serves it up as a MultiArray of type String which has
one less dimension.
