Presumably the Help system didn't say since that's a WINDOWS environment 
variable.  From the Windows XP Start menu....

   Select Settings
   Select Control Panel
   Double-click System control panel
   Click Advanced tab on System control panel window.
   Click Environment Variables button near bottom of the Advanced tab.
   In the lower* of the two panes in the Environment Variables window
     that opens, click the New button.
   Fill out the New System Variable window's dialog with the

     Variable name:  MATHEMATICA_USERBASE
     Variable value: C:\MyMathDirectory

   Now click the OK button there, then the OK button on the
     Environment Variables window, then the OK button on the
     System Properties window.

   (Re)start Mathematica.

[If you have more than one user, you could instead use the upper of the 
two panes and add the new environment variable as a per-user variable.]

There are other ways to get to the System Control Panel; I gave just one.
