del tot*
would delete files called total.arc, toto, totalitarian, etc. You can also
delete file names from more than one disk drive by specifying the drive
letter, as in
del a:total.arc a:games.arc c:frizbee c:frazzle
arc/c
Create your own archive file. In creating a file, you need to specify
on which drive(s) the component files are to be found, and the exact
filename of each file you wish to have included in the archive file. ARC
can only handle eight individual filenames at a time. If you need to
include more than eight filenames, you can either create an archive file
with eight names and then add to it (see the instructions under arc/a
below) or you can transfer all the files to a blank disk and then "arc" the
entire disk. As before, if the filename includes a space, be sure you type
in a SHIFTED space in that place.
One thing you may wish to do is to mark the file with the current
date. You'll notice that the ARC program displays a date when it is first
loaded and run. This date will appear on all your files. To change the
date, type
date (day),(month),(year)
(using numbers, of course) on a separate line before you begin to create
the file. ARC uses the European convention of putting the day first,
rather than the American form which puts the month first, so you would type
24,11,1988 for example.
Here's how the arc/c instruction would appear if you were using a
single disk drive to create an archive file called TOTAL out of individual
files called ONE, TWO, THREE, and FOUR.
arc/c total one two three four <return>
Note the space between the arc/c and the file name. That space is
essential. And since you're using only one drive, you don't have to
specify the drive with a letter.
After you've typed in that command, ARC will give you an author's
credit message and will begin creating your archive file. It will tell you
which form of compression, if any, it's using on the component files, and
it will also tell you when the file is finished. The finished file will be
called total.arc.
(Note: Some versions of the program may give you the message "60, write
file open" at the end of the file creation process. This does not mean
that the arc command has failed, unless the red (1541) or green (1571)
light on your drive stays on. It simply indicates that you can add to the
arc file at a later date if you wish.)
If the files you wanted to put into the arc file were on different
disk drives, you'd specify the individual drive by letter in the command.
It might look like
arc/c a:total a:one a:two c:three c:four <return>
Meaning that you were creating the archive file TOTAL on drive a using
files ONE and TWO from drive a and files THREE and FOUR from drive c.
If you want to archive the contents of an entire disk, using one
drive, the comand would be
arc/c total a:*
For two drives, you'd specify source and destination drives, as in
arc/c a:total c:*
arc/a
This command adds files to an arc file you've already created. For
example, if you wanted to add files FIVE, SIX, and SEVEN to the file you
created above as total.arc, you'd type
arc/a a:total a:five a:six c:seven <return>
NOTE: don't use this command to add files to an undissolved arc file
you've downloaded using Xmodem. Xmodem "pads" the files to make them an
exact number of blocks long, and if you append files to a file that's been
padded this way, you won't be able to dissolve the file into its component
parts later. If you want to add to a a file you've downloaded, dissolve it
first with arc/x and then re-archive the files.
arc/l
This command can be used to list all the component files of an archive
file. You can use it to see what's in a file you've downloaded, or to
check a file you've created to make sure you've included everything you
planned to. Note that this doesn't separate the file into its component
parts; it just lets you see what the parts are. If you typed
arc/l total (or total.arc)
