Hi sir,
I tried this method but still it is not working,
His common block is,
atom.common(common block)-COMMON atmosCommon, atmos, H, metals, molecules, nHmin

I have written a program as you said like this,
pro test1
common atmosCommon,atmos
atmos.vturb(*,*)=2500.0000
return
end

I have called this in the function(read2datmos.pro),

FUNCTION read2datmos, fileName, BFILE=Bfile
Nx = 0L & Nz = 0L & NHydr = 0L

openr, unit, fileName, /GET_LUN, /XDR

readu, unit, Nx, Nz, NHydr
point_lun, unit, 0

atmos = {Nx: Nx, Nz: Nz, NHydr: NHydr, $
boundary: lonarr(3), dx: dblarr(Nx), z: dblarr(Nz), $
T: dblarr(Nx, Nz), n_elec: dblarr(Nx, Nz), $
vturb: dblarr(Nx, Nz), vx: dblarr(Nx, Nz), $
vz: dblarr(Nx, Nz), $
nH: dblarr(Nx, Nz, NHydr)}

test1 (I have called the program here).

But still it is not working.

Will please let me know if there is any mistake.
thanking you
