Trying to follow this question up, I discovered that in my Windows
IDL 5.2 version that I couldn't even use the HDF_BROWSER and
HDF_READ together without causing an error. RSI technical support
now confirms this is a bug with no known workaround.
So--just so some of the rest of you don't think you are
going crazy too--here is what happens to me when I try to use
these two programs together:
IDL> Print, !Version
{ x86 Win32 Windows 5.2 Oct 30 1998}
IDL> template = hdf_browser('testhdf.hdf')
IDL> output_structure = HDF_READ('testhdf.hdf', TEMPLATE=template)
% Variable is undefined: COMPARE_STRUCTURES.
% Execution halted at: HDF_READ
% $MAIN$
I created the HDF file by running the WRITEHDF program on my
web page:

I'll let you know if I learn anything more.
Cheers,
David
