A minor footnote to the little program: In IDL V5.3 or later, the 5 lines

numbers = IntArr(N_Elements(files))
FOR j=0,N_Elements(files)-1 DO BEGIN
stringpart = StrMid(files[j], 5, 3)
numbers[j] = Fix(stringpart)
ENDFOR

can be replaced by the single vectorized line:

numbers = fix(strmid(files,5,3))
