UPDATE.DOC, ARJ 2.50 October 1995
This documents new or updated information since ARJ 2.41.
** IMPORTANT NEWS ****************************************************
THIS VERSION OF ARJ IS AN OFFICIAL RELEASE.
The mailing address of ARJ Software has changed as of August 1993.

There is ARJ Internet mailing list and WEB site support
information added to the file ARJ.DOC.
Beginning with this version of ARJ, full functionality of certain
ARJ software features will NOT be available in the shareware
versions of ARJ (registered or not). These features include the
multiple volume self-extractor, the ARJSFX embedded command line
feature, and the inhibit display messages option. The full
featured versions will ONLY be available from ARJ Software and
its agents. Registered ARJ users can upgrade to this version for
a small shipping/handling fee ($5).
See ARJDISP.DOC for information about a new feature for software
distributors using ARJ.
Check the WHATSNEW.DOC file for changes since ARJ 2.41a.
The new multiple volume self-extraction function is LIMITED in the
ARJ shareware version. Only volumes of 360K or less in size can be
created AND only such volumes will be processed by the
self-extractor. This feature is accessed through the "-je" option
along with the "-v" option.
The ARJ Security envelope scheme in 2.50 is the SAME as in 2.41.
In other words, ARJ-SECURE 2.50 is compatible with 2.41. There is
no change in the envelope key files. However, the 2.50 version
of this ARJ-SECURE is able to make an archive and "seal" it with
the same command line. ARJ-SECURE users can upgrade to this
version for a small shipping/handling fee ($5).
ARJ can archive up to 32,000 files at one time when the new "-hm"
option is specified. This option enables ARJ to use disk space
instead of memory space to manage the names of the files being
archived.
Please note that older versions of ARJ.EXE will NOT process the
new multiple volume self-extractor. An error message will be
displayed.
A new option "-w" sets the ARJSFX module to skip the "Continue
extraction?" message. This is a change from the former method to
inhibit the message.
The extraction messages of the large ARJSFX module have been
shortened in default mode. A new "-k" option will display the
long form of the messages.
It is now possible for registered ARJ users to control whether
the ARJSFX module will display the overwrite, create directory,
and continue extraction prompts without requiring command line
options. It is also possible to control the ARJSFXJR overwrite
behavior.
A diskette change test will detect the failure to swap diskettes.
This can cause a problem for those who put more than one volume
per diskette. However, this diskette change test is limited to
three retries, so ARJ will eventually accept the non-change of
diskette. The user can inhibit this change test with the new
"-vi" option.
Whenever archiving to diskettes, it is HIGHLY recommended that the
option "-jt" be used. This helps spot BAD diskettes or BAD
diskette drives. It is HIGHLY recommended that the "-jt" option
be used in a Windows or multi-tasking or network environment.
UNERASE or UNDELETE commands do not always recover a file
correctly. This will result in damaged archives. This is true
for all archive types. You should always test an archive after
unerasing it.
If you use the software disk cache, HYPERDISK, see the KNOWN ARJ
ISSUES section in ARJ.DOC for important information.
CAUTION: To those who use the -t1 and/or -t1g options to save a few
extra bytes. This option should only be used on TEXT FILES. Those
are files created by EDLIN, EDIT, QEDIT, BRIEF, NOTEPAD, and
others. Text files typically contain only letters, numbers,
spaces, and punctuation marks. WORD PROCESSOR format files ARE NOT
TEXT FILES! MS WORD, Wordperfect, AMIPRO, WRITE, and similar files
ARE NOT TEXT FILES. Using the -t1 or -t1g on any other kind of file
probably will result in DATA LOSS!
**********************************************************************
USER PROMPTS
The ARJ user prompts have been improved to provide more
flexibility. In addition to the normal yes and no responses, ARJ
also accepts the following responses: quit, always, skip, global,
and command.
"Global" sets ARJ to inhibit all subsequent user prompts by assuming
YES for all queries as if "-y" were specified.
The "Always" response has changed. It now sets ARJ to assume YES
for subsequent queries of the same class. For example, answering
YES to the overwrite query will assume YES for ALL subsequent
overwrite queries.
"Skip" sets ARJ to assume NO for ALL subsequent queries of the same
class.
Subsequent user prompt messages will still be output to the screen
after the "always" and "skip" responses but no user response will be
accepted.
"Command" prompts for one DOS command and then executes it. ARJ
then returns to expect an answer to the current yes/no query. You
should keep the query in mind as ARJ does NOT always redisplay
the full query message.
ARJ ERROR LEVELS
ARJ will now return a DOS errorlevel of 9 when trying to process a
file that is NOT an ARJ archive.
With the new option "-hl", ARJ will return a non-zero errorlevel
when a user specified filename from within an ARJ listfile cannot
be found on disk. Ordinarily, ARJ returns no error for such a
situation.
ARJ ARCHIVE NAME WILDCARDING
ARJ allows the wildcarding of the archive parameter for ARJ
commands other than the add commands (a, f, j, m, u). If the "-r"
option is specified, ARJ will scan through subdirectories looking
for ARJ archives to process.
This feature allows a user to delete a specific file from a series
of archives.
Example: ARJ d *.ARJ bbs.ad
This feature could also be used to extract a series of archives.
Example: ARJ e *.ARJ
The new "-hr" option allows ARJ to process multiple archives that
cause errors.
ARJ COMMAND LINE PROCESSING
For non-add type commands, ARJ will now always use the full
specified pathname for selecting files within an archive by
matching against the full specified pathname.
Example: ARJ x archive d:\temp\ f:\data\1994\report.txt
ARJ will now accept an ARJ command line from a response file as in
"ARJ @command.rsp". The "@" symbol indicates that the appended
name is the name of the response file. In this case, the file is
command.rsp. The response file symbol cannot be changed.
The response file should contain the ARJ command line minus the
initial "ARJ". The command line may be split over as many lines
as necessary. The response file feature will NOT accept QUOTED
command line options. Options with embedded blanks ("-vasTEST X")
will not be processed as expected. When using the response file
feature, ARJ will accept only the "-+", and "-&" switch options on
the DOS command line along with the response file name. All other
command options must be specified in the response file or in the
ARJ environment variable.
ARJSFX COMMAND LINE PROCESSING
All of the ARJ self-extractors feature a new option to embed any
command line options into the self-extracting a
