Hi Joe,

Last week, in response to your question

> Which is preferred?  NC_LONG or NC_INT?

I replied:

    The C++ interface still supports the netCDF-2.4 typedef "nclong", which
    was defined to be an int on most platforms but a long on a few.

    We deprecated the use of "nclong" with the netCDF-3 release, but
    unfortunately never updated the C++ interface to use NC_INT instead
    of NC_LONG and "int" instead of "nclong".

    I thought I had fixed this in a way that would keep backward
    compatibility for our next release (3.4), but in researching your
    question, I discovered some additional changes that need to be made.
    The goal is to have interfaces overloaded for both int and long
    instead of nclong.

    For now, I'm afraid you'll have to use NC_LONG and cast (ugh) to
    nclong to use the existing C++ interface for putting ints.  If you
    can wait a week or two, we may have a beta test version with the
    necessary changes incorporated.

The changes to eliminate the necessity for using nclong casts or the
NC_LONG type are now available as a patch from the "Know Problems with
netCDF 3.3.1" page at

    http://www.unidata.ucar.edu/packages/netcdf/known_problems.html#cxxnclong

in case you're interested.
