    Actually, PostScript does have open files; find a Red Book, look up the
    "file" operator, and follow the pointers to elsewhere. (Many/most
    PostScript-capable devices do not have anything of significance by way
    of a filesystem, but that's a different issue entirely.)

    And if you actually read the Red Book, _you_'d get a better
    understanding. In the Second Edition Red Book, for example, you'd want
    to read section 3.8, "File Input and Output".
