Yes, I know that those environment variables give values to the corresponding Mathematica variables. But that doesn't solve the problem of setting different values of $BaseDirectory and $UserBaseDirectory for two different versions of Mathematica installed at the same time - without somehow changing the corresponding Windows environment variables (manually or with a batch file to start Mathematica). What I was asking about/suggesting was a new feature that would allow setting these in the Options Inspector. (That was what the original posting was about.)
