c parameters which need to be set by the user:

	integer lz    ! max ldb, # of z (parallel) grid points +1
	integer mffty ! max nffty, # of y (poloidal) grid points
	integer mfftx ! max nfftx, # of x (radial) grid points
	integer nez ! max # of time points saved -- should be large enough
		    ! to allow good resolution of important frequencies.

	integer ndomz,nconz	! ndomz: max # of different FFT lengths
				! nconz: max # of connected FFT domains
	integer kz		! max # of grid pts. in kappa (pitch angle)

	parameter (ndomz=1,nconz=1)  ! required for iperiod=0,1,2
c	parameter (ndomz=2,nconz=2)  ! larger values needed for iperiod=3
	parameter (lz=65, mffty=32, mfftx=32, nez=205, kz=lz)

	integer nspecz 	! max # of different species
	parameter (nspecz=1)

       	integer fno   ! number of files postc can concatenate
	parameter(fno=1)

	complex ii
	parameter (ii=(0.,1.))

c ********************************************************************
c derived parameters (not set directly by the user):
c The following parameters should be odd, or not contain many factors
c of 2, to avoid "memory bank conflicts" and improve performance on
c CRAY computers:

	integer mzz
	parameter (mzz=mffty+2) ! extra room for complex/real array 
		! equivalences in y,ky fft's (yspace.f, etc.).

	integer nzz
	parameter (nzz=mfftx +1)

	integer mz  ! max # of spectral modes in the y-direction (poloidal)
		    ! (only ky>=0 modes are kept)
	parameter (mz=(mffty-1)/3 +1)

	integer nz  ! max # of spectral modes in the x-direction (radial)
		    ! (including +kx and -kx modes)
      	parameter (nz=2*((mfftx-1)/3)+1)
