Reggie,

A "permission denied" error message indicates that the operating system
won't allow your program to create the associated file.  This probably
has nothing to do with the netCDF library.  Reasons for denying this
permission include the following:

    1.  The file name is invalid.

            Put some quotes around the filename to see if it contains
            any embedded, illegal characters.

    2.  The directory in not writable by you

            Try creating a file in the directory by another means.

    3.  The disk is remotely-mounted read-only.

            Try creating a file in the directory by another means.

    4.  The disk is full.

            Try creating a file in the directory by another means.

    5.  The file already exists but cannot be deleted as the semantics
        of "nf_clobber" demand.

            See if the file exists and check its permissions against
            those of your program.

I do not see how changing the type of the filename-containing variable
could change the behavior of the program.
