   6 *Purpose:
   7 *   This file defines the modeflag values for spawnxx calls.  Only
   8 *   P_WAIT and P_OVERLAY are currently implemented on DOS 2 & 3.
   9 *   P_NOWAIT is also enabled on DOS 4.  Also contains the function
  10 *   argument declarations for all process control related routines.
