Unfortunately, there are no mechanisms in Mathematica's Export function for specifying set names. You may want to use a tool like NCSA's hdfed to add the desired set names. http://hdf.ncsa.uiuc.edu/hdftools.html > Also, the on-line help for the Export function says that HDF format is > "supported for numerical and textual data" but I can't figure out how to > export a text string. If you are working with an eight-bit character encoding, you could transform the string into an array of characters (e.g. like what is returned by the built-in Characters function) and then write out the array as Byte data types. -- P.J.
