We don't have anything here at Unidata to do the conversion or ADDE
access of HDF data.  It could be that some folks at NASA/MSFC
(Marshall Space Flight Facility) have such code.  The reason I mention
this is that they make GOES data available by FTP in HDF and McIDAS
AREA formats.  Perhaps your student could:

o get the data she needs from MSFC:

ftp://rsd.gsfc.nasa.gov/pub/Weather     all GMS/GOES 8 + 10
ftp://geo.msfc.nasa.gov/Weather         all GMS/GOES 8 + 10*
ftp://explorer.arc.nasa.gov/pub/Weather all GMS/GOES 8 + 10
ftp://weather.cs.ucl.ac.uk/Weather      GMS-5 only

o find someone at MSFC who has a HDF to AREA converter

The location of the dataset wasn't defined in your session or the
dataset is not defined at Wisconsin?

Right.

Right.

>but this is not being done (not automatically anyway).

It is always done automatically.  MCTABLE.TXT is the place applications
look to find out if a dataset is local or on a remote machine.

>Should this be in a .mcenv for me (indeed, each user), because
>I don't have one currently?

You can define the environment variables MCTABLE_READ and MCTABLE_WRITE
in your environment.  Please refer to:

http://www.unidata.ucar.edu/packages/mcidas/mcx/config_users.html

for details.

Given that you are in the mode of setting up a new user account,
you really should review the information that is available under
the:

Configuring Unidata McIDAS-X Accounts
http://www.unidata.ucar.edu/packages/mcidas/mcx/config_mcx.html

page of online documentation for McIDAS-X.  All of the information
you need is there, so it will be easier than me reiterating it through
email.
