I should think something like this might work:

files = Findfiles('surfout.*', Count=numFiles)
files = files[Sort(files)]
FOR j=0,numFiles-1 DO BEGIN
OpenR, lun, files[j], /Get_Lun
etc.
etc.
Free_Lun, lun
ENDFOR

Be sure to check the file names before you use
this code. Findfiles returns names in a strange order
sometimes. It seems almost random to me. You might
have to experiment with a better way to sort the
names if the order is important to you.

Cheers,

David
