; Create a blank file ready to receive data
data = FLTARR(256,256)
OPENW, lun, writename, /GET_LUN
FOR i = 0, 99 DO WRITEU, lun, data
FREE_LUN, lun
OPENU, datalun, writename, /GET_LUN
A = ASSOC(dataLun, data)
; Perform some genius processing of your choosing
FOR i = 0, 99 DO BEGIN
newFrame = FLTARR(256,256) + i
A[i] = newFrame
ENDFOR
I believe this is the general way I did things.
