Thank you -- but OUCH!
I do not want to have "Mathematica" automatically appended to the path I
specify! My directory structure has, under D:\Math, several separate
directories for different versions of Mathematica
(D:\Math\Mathematica4.0, D:\Math\Mathematica4.2, etc.)
In order to use all my AddOns (except Standard AddOns), especially
Applications, with all versions of Mathematica -- without having to
maintain multiple copies of these AddOns -- I want a separate directory
D:\Math\AddOnsMma for them (and then have subdirectories Applications,
etc., of that.
With the effect you describe of setting, say
MATHEMATICA_ADDONS=D:\Math\AddOnsMma, then this would force everthing
there to be buried one directory deeper than I want -- into
D:\Math\AddOnsMma\Mathematica.
On the other hand, if I set, say MATHEMATICA_ADDONS=D:\Math, then that
would be obviously (?) undesirable: the directory would be
D:\Math\Mathematica, which is obviously too much like the names of the
top directories I'm using for the different versions of Mathematica itself.
Why in the world was the design decision made to automatically append
"Mathematica" to what those environment variables specified? Is there
some decent way around this?
