My first stop with a new HDF file is to see if I can read
it in my ncdf_browser.

http://www.dfanning.com/ncdf_browser.zip

If I can, then I can just read the variables out to the IDL
command line from the browser, or I can use the software
to read the variables programmatically.

If I need something fancier than that, I usually go get
Liam Gumley's HDF tools:

They almost always work. :-)

Cheers,

David
