$DIR

*****~**********
You
might
ask why there is a need for the number of blocks,
when
you
already have the filesize in Kbytes?
Well,
this is not too simple.
In
the worst case, a file can waste up to 16 Kbytes of valuable disk space,
though
it actually consists of but one block.
Thus,
beth numbers
are
indicated to enable you to recognize such files.
The bottom line tells you how many files have been found,
how much room
they occupy and,
after all,
how much space there rema1ns on that disk.
You
are further informed that more files would properly have had to
be
indicated,
but these files are "hidden" by a "SYSTEM" attribute attach-
ed. You can make those files "visible" by activating an option.
If you are not interested in the entire directory, you are free to limit
the number of files which will be displayed: When you specify an ambigu-
ous filename, only those files are indicated which match the name speci-
fied. For example:
DIR *.COM
displays all files of the "COM" type.
DIR
*.*
displays all files, having the same effect as
DIR
C.B.l. $DIR Options
The
directory display format as explained above has a
certain
feature
which
can
sometimes be disadvantageous:
the files are listed page
by
page,
and the screen is erased before a new page appears.
Besides, you
may occasionally want to see the time stamps.
For these and some
other
requirements,
$DIR has a number of options.
You will already know what
options are.
