Strange, but neither MATHEMATICA_ADDONS nor MATHEMATICA_USERADDONS seems
to be documented in the Help Browser. At least these do not appear in
the Master Index and are not mentioned in the section on File Layout.
Further, they do not behave quite the way you say. As a system variable
I set
MATHEMATICA_ADDONS
to have value d:\Math\AddOns; as an enviroment variable for
Administrator I set
MATHEMATICA_USERADDONS
to have that same value.
When I start Mathematica afterwards, the values are
$AddOnsDirectory
d:\Math\AddOns
$UserAddOnsDirectory
d:\Math\Addons
-- without any "\Mathematica" appended thereto!
Further, the directory d:\Math\AddOns now has subdirectories
Applications, Autoload, FrontEnd, Kernel, Licensing, SystemFiles. Under
the FrontEnd directory there, there is now a very short init.m
consisting of:
SetOptions[$FrontEnd,
AutoOpenNotebooks->{},
ScreenRectangle->{{0, 1280}, {0, 979}}
]
Still in C:\Documents and Settings\Administrator\Application
Data\Mathematica\FrontEnd there is a considerably longer init.m, of the
kind I expect to see, beginning:
SetOptions[$FrontEnd,
NotebookDirectory:>FrontEnd`FileName[{ ...
This is after I held down Shift-Control when restarting Mathematica,
just to be sure preferences are restored to defaults.
So now I'm not only confused by the discrepancy between what you say the
two environment variables do and what happened, but also by the issue of
what kind of preferences are stored in what init.m's where.
I note that the Help Browser _does_ refer to a separate environment
variable MATHEMATICA_PREFERENCES.
