function h5ex_t_string
%**************************************************************************
%
%  This example shows how to read and write string datatypes
%  to a dataset.  The program first writes strings to a
%  dataset with a dataspace of DIM0, then closes the file.
%  Next, it reopens the file, reads back the data, and
%  outputs it to the screen.
%
%  This file is intended for use with HDF5 Library version 1.8
