_Special_Reminder_: ARK runs ONLY on Z80 systems. No support
is planned for 8080 systems.
Usage:
ARK [-bksw] <archive> <file1> . . . <filen>
-b retain backup of .ARK
-k force crunching
-s force no compression
-w supress warning messages
<archive> = name of archive file (default type = .ARK)
<filex> = file to be added to archive (wildcards and du:
are supported)
ARK presently supports three types of members: type 2
(uncompressed), type 3 (ncr encoding - 'packed'), and type 8
(Lempel-Ziv-Welch encoding - 'crunched'). ARK will choose the
most efficent method of compression and save the file using that
format.
In general, the command you will use to do most of your
archiving will be something like:
A>ARK d:archive e:*.*
Note that ARK will either add or replace members of the
archive, so you do not need to specify that it is an update.
(This example makes (or adds to) D:ARCHIVE all the files on E:.)
On systems supporting the BDOS T_GET (105) call, (which
includes Z80DOS, Turbo-DOS, MP/M, and I think CP/M+), the time
and date of each member in the archive is set to the current time
and date.
For those of you with Z80DOS-type date stamping, I have
included a file called ARKDATE.MAC that does date stamping for
individual files in an archive using the 'last-modify' date and
time stamp. As a side effect (which looks pretty neat, so I
left it that way) it sets the time/date to all zeros if there is
no date stamp for a file, which makes UNARC (and probably ARC as
well) put empty spaces in the date area of a file listing.
If your system insists on using something other than Z80DOS
type calls, then you're going to have to write your own overlay.
You are certainly welcome to use the one provided as an
example. (Just to put my money where my mouth is, even I must
use the overlay to make ARK get the dates from Z80DOS -- the
'standard ' version always uses an arbitrary date.)

version number information!) to:
