"Stacking" MOPAC or HyperChem

 Dear Netters,
      Does anyone know if it is possible to "stack" molecules in MOPAC
 or HyperChem 3.0 such that after an AM1 or PM3 calculation for one molecule
 is completed the programme will automatically go on to perform a like calcu-
 lation on a second molecule, hten a third molecule, &c.?  If it is indeed
 possible, kindly send detailed instructions.
      Thanks in advance to all responders.
