!   flush is one of the best named functions in fortran, although it does not do what I think it should.   This function flushes
!   the buffer to print unit i, so when the unit is flushed, all data written to the open file will appear in the file.
!   Not all compilers have this function.

         subroutine flush(i)
         implicit none
         integer :: i
         flush(i)
         end subroutine flush
!
!   number of command-line arguments.
!
         integer function mstm_nargs()
         implicit none
         integer nargs
!         mstm_nargs=nargs()
         mstm_nargs=iargc()
         end function mstm_nargs
!
!   command line argument retrieval
!
         subroutine mstm_getarg(char)
         implicit none
         integer :: istat
         character(*) :: char
