  21.    [Paul Abrahams wrote:]
  22.    Given the variances among operating systems, perhaps there ought to be a
  23.    convention that the first space-delimited item in each line produced by
  24.    open(dirname) is the filename.
  25.  
  26. This is not a bad suggestion.  Certainly the format of the string should
  27. follow conventions that preserve portability.  Some operating systems
  28. (Macintosh, and recent versions of Windows) allow spaces in filenames!
  29.  
  30.    This does seem close to my earlier suggestion that reading a directory
  31.    should act as a generator of the filenames within the directory.
  32.  
  33. That's because my current Windows directory reading facility was inspired
  34. directly by your suggestion.  It was a good suggestion, Paul!  It isn't
  35. technically a generator, although you can use the generate operator (!)
  36. to get a generator of filenames, as in:
  37.  
  38.     f := open(dirname)
  39.     every filename := !f do ...
