 For the answer to your question, "man runon".
 However, if GAMESS is like most quantum programs, it spends a lot
 of time in IO and cannot keep the CPU busy.  The net effect of
 doing what you propose might be to give each charmm run 50%
 of a CPU and to increase the GAMESS CPU utilization by very little.
 Still, you could try and see.
