Set is for enviromental variables ex: %systemdrive%, %path%, etc...
This does not configure a folder for you, but references one that is there already.

As an example:

At corporate headquarters
%PriServer% = SCorp
%AppServer% = SA_Corp

At a field office
%PriServer% = SFieldA
%AppServer% = SA_FieldA

At another field office
%PriServer% = SFieldB
%AppServer% = SA_FieldB

Now in my script I can just reference %PriServer% and use it to map everyones home drive to \\%PriServer%\Users$\Home\%UserName%

Or I need to launch a special application

Run \\%AppServer%\RunAtStart\WeAreWatching.EXE

So no matter where my servers are or what they are named I know that I have variable that I can use as a constant in my script.

Did that help any?
