I have a directory containing a series of files of the format:
A2008001231000.L2

I only care about the 6-8 digits, so the files are effectively:
?????---*.L2

I have files that range from ?????001*.L2 to ?????366*.L2

It should be noted these three digits represent the julian day of the files. My goal is to be able to define two variables: start_day and end_day. How can I list off all the files between start_day and end_day. NOTE: Since the julian days must be 3 digits long, it complicates matters.
