I'm sorry, maybe I didn't make myself clear or you're just missing the
point. Example :

 Let's say there's a directory DH0:programs/graphics/sculpt/objects 

Then I wanna type : NCD objects

and the computer should automaticaly know where that directory is located
( I don't care how) and perform a : 

CD dh0:programs/graphics/sculpt/objects 

It also should not matter in what directory I am on the moment of giving
the NCD command.
