The INFO & SHOW programs are disk parameter utilities written by Glenn F.
Roberts & described by him in his article "Finding Disk Parameters" starting
on page 112 of the May 1986 issue of PC Tech Journal.
Usage:

        INFO  [d:]

        where d: is an optional drive specifier; information is displayed
        about the current or specified drive.



        SHOW [[d:]filename.ext [a:]]

        where d: & a: are optional drive specifiers & filename.ext is an
        optional file name; information about the named file (or default *.*)
        is displayed, including attributes (a=archive, h=hidden, s=system,
        r=read-only) & cluster chains.  If the 2nd drive specifier is included,
        the amount of space the file(s) would occupy on that drive is listed;
        this can be used to see if a floppy disk will hold the file(s).
