Oh, dear! You probably only need two of these, at most. One to read the
data files (closing it after reading each file) and one to write the
results to the output file.

Something like this:

outLun = Get_Lun()
FOR j=0,numFiles-1 DO BEGIN
thisFile = files[j]
OpenR, inLun, thisFile, /Get_Lun
ReadF, inLun, ....
Free_Lun, inLun
... whatever you do to manipulate the data here
PrintF, outLun, manipulatedData
ENDFOR
Free_Lun, outLun

Cheers,

David
