Whoops! Forgot to open that output file!

outLun = Get_Lun()
OpenW, outLun, outputfileName
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
