DARJ v1.0 A CP/M program to provide a directory of files within .ARJ
archives.
Paul R. Hunt, August, 1991.
Acknowledgement: DARJ is a port of AV.C by Robert K. Jung (c) 1990.
Conditions of use: The programs and documentation in this package must
not be altered in any way. In particular, the name Robert Jung, and my
name must stay in tact in the programs and documentation. I accept no
liability for any problems or claims arising from the use of this program.
This package must be distributed in its entirity. Otherwise, use freely
and distribute liberally!
INTRODUCTION:
This program is used to provide a directory of the contents of a .ARJ
archive file. The companion program, CPMUNARJ, is used to extract files
from .ARJ archives.
This program was compiled under CP/M Plus. However, no CP/M Plus specific
functions are used, so it should run under CP/M 2.2 as well. NOTE,
however, that this program will ONLY run on a Z80 processor.
USING DARJ:
The program is used as follows:
DARJ [du:]<archive>[.arj]
<archive> is the name of the archive file. If no file name extension is
specified, the extension .ARJ will be assumed. A drive and user
specifier may optionally be used. For example, the following command:
DARJ C3:MYARJ
will open and display the file MYARJ.ARJ on drive C:, user 3. If the
archive actually has no file name extension, then the file name should be
terminated with a full-stop.
If the archive file is found, a directory similar to the following will be
displayed. (The data in the last column is really only of relevance to the
full-featured archiving system by Jung).

'Original' and 'Compressed' refer to the original and compressed file sizes
respectively, in bytes.
The second last field, 'Attr', is the file attribute field. Each of the
four columns in this field indicate a file attribute. This is not the
place to discuss MSDOS file attributes, but, briefly, they are as follows:
Col. 1 : Archive Bit. 'A' indicates archive bit set, else '-'.
Col. 2 : System Bit. 'S' indicates a system file, else '-'.
Col. 3 : Hidden Bit. 'H' indicates hidden file, else '-'.
Col. 4 : Read Only. 'R' indicates Read Only, else 'W' (read/write).
The last field, with the enlightening name of TPMGVX, gives a little more
detail about each file as follows:
T -> File Type (B = Binary, T = text)
P -> A '+' indicates path information is available.
(Not available from DARJ, nor relevant to CP/M)
M -> compression method used
G -> A 'G' indicates file is garbled (encrypted).
V -> A 'V' indicates archive is continued in another volume.
X -> An 'X' indicates file is part of a larger file.
NOTES:
DARJ was compiled using HI-TECH C v3.09 for Z80 CP/M.
