Start each do-file with -clear all- rather than just -clear-.

-clear- without -all- removes

    1.  data 
    2.  value labels

-clear all- removes the above and removes 

    3.  matrices (Stata)
    4.  scalars  (Stata)
    5.  constraints 
    6.  clusters
    7.  save results
    8.  sersets
    9.  Mata functions        <--
   10.  Mata matrices         <--
   11.  other Mata objects    <--

Ekatrina noted that -clear mata- seemed to solve the problem.  -clear mata-
removes (1), (2), (9), (10), (11).  

-clear all- is best.
