Well, your XINTERANIMATE loop is just a bit wrong. I'd
do it like this:

   ; Get the Filename
   openr, 1, 'E:/Temp/batch.rvd'
   datas=fltarr(3,36,49,22)
   readf, 1, datas
   close, 1
   h=rebin(reform(datas[2,*,*,*]), 72, 98, 22)
   loadct, 3
   XINTERANIMAGE, Set=[512, 512, 22], /Showload
   FOR j=0,21 DO BEGIN
	Shade_Surf, h[*,*,j], ZRange=[-1, 1]
       XINTERANIMATE, Frame=j, Window=!D.Window
   ENDFOR
   XINTERANIMATE
   END

I'd add a DEVICE, DECOMPOSED=0 to the top of the file. :-)
