SUBROUTINE savedata(Nx,Ny,Nz,plotnum,name_config,field,decomp)
!--------------------------------------------------------------------
!
!
! PURPOSE
!
! This subroutine saves a three dimensional real array in binary
! format
!
! INPUT
!
! .. Scalars ..
! Nx = number of modes in x - power of 2 for FFT
! Ny = number of modes in y - power of 2 for FFT
! Nz = number of modes in z - power of 2 for FFT
! plotnum = number of plot to be made
! .. Arrays ..
! field = real data to be saved
! name_config = root of filename to save to
!
! .. Output ..
! plotnum = number of plot to be saved
! .. Special Structures ..
! decomp = contains information on domain decomposition
! see http://www.2decomp.org/ for more information
! LOCAL VARIABLES
!
! .. Scalars ..
! i = loop counter in x direction
! j = loop counter in y direction
! k = loop counter in z direction
! count = counter
! iol = size of file
! .. Arrays ..
! number_file = array to hold the number of the plot
!
