Re: Reading into arrays with order > 2

Hi Steven,

You are trying to read into a subscripted variable which is passed to
readf by value
and not by reference so when readf finishes all3MomData is unchanged.

this should work (assumimg that all3MomData matches the file format,
size+data type)

temp=reform(all3MomData[0,*,*])

for i=0, n_elements(names3Mom)-1 do begin
  openr, lun, names3Mom[i], /get_lun
  readf, lun, temp
  all3MomData[i,*,*]=temp
  free_lun, lun
endfor


good luck, 
	Ivan
