Nuprl Lemma : C_LVALUEco-ext

C_LVALUEco() ≡ lbl:Atom × if lbl =a "Ground" then C_LOCATION()
                          if lbl =a "Index" then lval:C_LVALUEco() × ℤ
                          if lbl =a "Scomp" then lval:C_LVALUEco() × Atom
                          else Void
                          fi
