If you downloaded the HDF5 Write DLM, a help file
"HDF5_Write_Support.pdf" should have been installed in your
/RSI/IDL61/help/ directory. There are examples in there showing how to
create and write to HDF5 files.
Cheers,

IDL has had the HDF 5 read routines since IDL 5.6. Just recently, RSI
put a DLM on their website which allows you to actually write HDF 5
files. The DLM drops into an existing IDL 6.1 installation. The more
exact link is here: http://www.rsinc.com/idl/addons_hdf5.asp

The IDL on-line documentation lists a bunch of routines
named H5****** that appear to be routines to read HDF5
files. I don't see anything that looks like it allows
you to write these kinds of files.

Hello,
from IDL you can run the following commands to see what hdf library you
have.
HDF_LIB_INFO, MAJOR=MAJOR, MINOR=MINOR, VERSION=VER, RELEASE=REL
PRINT, 'IDL ', !version.release, ' uses HDF Library ', $
MAJOR, MINOR, REL, FORMAT='(A,A,A,I1,".",I1,"r",I1,A)'
PRINT, VER
end
Here is the result I get
IDL 6.1.1 uses HDF Library 4.1r5
NCSA HDF Version 4.1 Release 5, November 5, 2001
I don't use HDF, but it appears that version 5 (of hdf) is not available
in the regular install of IDL v6.1.1. If you go to http://rsinc.com/ you
can find that you
can download the hdf 5 DLM.
Anyways, there is some example code at
c:\RSI\IDL61\examples\data_access\sdf\hdf_info.pro
also look at
c:\RSI\IDL61\examples\data_access\sdf\hdf_rdwr.pro
(these paths are a likely one for a ms windows machine, if you have a
different platform, the full path will be slightly different)
Cheers,
bob
