You'll need to create a temporary variable to hold the data being read
and then store that temporary data into the struct. A "feature" in
the way WAVE handles structure tags is that they cannot get assigned
directly from a function call keyword (also true for IDL).

Something along the lines of this ought to work:

tdata = intarr(2, /nozero)
data = intarr(2, 400, /nozero)
openr, lun, file, /get_lun
for i = 0, 399 do begin
readu, lun, tdata
data(*,i) = tdata
endfor
