Hi John,

We haven't seen this problem, and I can't reproduce it.  Could you
give me an example of what you mean by a "large number"?  For example,
Java has no support for unsigned ints, so if you have an integer value
that's larger than 2^31=2147483647, its not an int but a long.  NetCDF
has no support for longs (64-bit integers), so you have to use doubles
to store numeric values that require more precision than an int or a
float. 

> JDK 1.1.8 on Linux works great.  Is this a limitation with Java 1.1.4?

Not as far as I am aware.  But if you can send a small example that
demonstrates the problem, we'll look into it ...
