Well, after I hit the SEND button I realized I really
didn't show you the neatest trick of all. The data
array should really be created with the Make_Array
function like this:

OpenR, lun, filename, /Get_LUN
sizeInfo = LonArr(5)
ReadU, lun, sizeInfo
data = Make_Array(Size=sizeInfo)
ReadU, lun, data
Free_Lun, lun

Cheers,

David
