| Unfortunately, acl I use does not maintain :directory and :file key
| parameters.

  the function EXCL:ARGLIST reports the argument list of a function, as
  does the Emacs/Lisp Interface function FI:LISP-ARGLIST, ordinarily bound
  to C-c a and M-A in Lisp mode or in a Listener.

(directory <wildpathname> :directories-are-files t)

  will return the subdirectories are ordinary files, and is the default.

(directory <wildpathname> :directories-are-files nil)

  will return the subdirectories as directories.

  note that Allegro CL distinguishes a file from a directory by the
  trailing slash in the pathname print syntax.

  all of this is well documented in the accompanying manuals or on-line
  documentation.  please take the time to read them.
