Hi Amita,

We don't provide support for the IDL interface, but NCDF_CONTROL
is evidently calling the netCDF function nc_enddef, and the
documentation for that function 

  http://www.unidata.ucar.edu/netcdf/docs/netcdf-c.html#nc_005fenddef

says it can return an error for several reasons, including:

    * The specified netCDF dataset is not in define mode.
    * The specified netCDF ID does not refer to an open netCDF dataset.
    * The size of one or more variables exceed the size constraints for 
whichever variant of the file format is in use). See Large File Support. 

The netCDF error -45 corresponds to the error "Not a netcdf data 
type", which may mean you are trying to create a variable or
attribute using a type code that doesn't correspond to one of
the five numeric types or one character type that netCDF-3 permits.
