On my system that key has the value
D:\Documents and Settings\Hadfield\My Documents
It seems odd to put programs in a "documents" directory. I should think
a more suitable location (and a better match to ~/myprog/ on Unix) is
one level up, ie
D:\Documents and Settings\Hadfield
On my system the latter directory is available as an environment
variable, USERPROFILE. It would be easier to access an environment
variable than to read the registry.
This is a Windows 2000 system--I don't know about Windows 9x.
You may also be interested in how IDL addresses this issue. The
documentation says the following under environement variables:
HOME
IDL uses the value of the $HOME environment variable when storing
user-specific information in the local file system.
Note
------------------------------------------------------------ --------------------
Under Microsoft Windows, the HOME environment variable may not be set in
all cases. If it is not set, IDL first attempts to substitute the
USERPROFILE environment variable (which usually looks something like
C:\Documents and Settings\username where username is the login name of
the current user). If USERPROFILE is not set, IDL uses the value of the
first of the following it finds: the TEMP environment variable, the TMP
environment variable, the Windows system directory.
------------------------------------------------------------ --------------------
Finally, note that in IDL 6.1 the APP_USER_DIR and APP_USER_DIR_QUERY
functions were added to support storage of user-specific info.

Not that this is the easiest way but this would be a very simple .dlm to
write. With Ronn Kling's "Calling C from IDL" it would probably only
take you a few hours, even if you are a C novice. For hints, you can
check out my directInput.dlm. It contains an couple of unrelated
functions to get system metrics. you could chop out all of the
directInput stuff and use these are starting points.
On the windows side there are a number of ways to set/get keys. The
Win32 api would probably be easiest if you are unfamiliar with MFC.

If you get this up and running, please share! :)

since I like perl in combination with spawn, I suggest:
Win32::Registry::File - Perl interface to MS-Windows registry files

Maybe getenv(/environment) gives, what you are looking for.
