If I understand correctly, you don't have a list with file names, but
you want to create it? If yes, I normally use FILE_SEARCH function to
generate a list of images that have to be processed:

list = FILE_SEARCH(directory+'*.fits')

Once you have it, you can run

FOR i = 0, nimages DO your_pro(list(i))

Check IDL help for the details of FILE_SEARCH:
