Are you using C, Fortran, C++, or perl?  The way to do it with each of
these languages is different.  For guidelines that show what functions to
call from C or Fortran, you could look at the section of the User's Guide
titled "Reading a NetCDF File with Known Names", which is also available
on-line at

    http://www.unidata.ucar.edu/packages/netcdf/guide_6.html#SEC34

For examples of reading character variables from C and Fortran, you might
also want to look at the section "Reading and Writing Character String
Values", in the NetCDF User's Guide and also available on-line at

    http://www.unidata.ucar.edu/packages/netcdf/guide_9.html#SEC68
