.H1;General Information
Guide Page

User 2-4 3+ Startup  diskettes containing the 3+ Prep file in their
System Folder can be used on any Macintosh netstation.  However,
saved startup configurations will not work when using the 3+   Startup
diskette on a Macintosh netstation connected to different
AppleTalk network (because this confuses the 3+ Prep file).

User 2-4 If your Macintosh netstation beeps during startup it
indicates that 3+ for Macintosh has failed installation.  The 3+ icon
in the Welcome to Macintosh box will be displayed with an X through
it, indicating an unsuccessful startup.

User 2-4 When booting your Macintosh netstation with 3+ for
Macintosh, be sure not to hold down the 3 key (character key on the
keyboard, not the keypad 3).  Holding down this key prevents the 3+
for Macintosh system files from loading properly, and you will not be
able to login.

User 2-6 When using the 3+ network, the Chooser must indicate
that AppleTalk is Active at all times.  If you click Inactive, your
netstation will not be able to access the server.  If this occurs,
open the Chooser from the Apple menu, click the AppleTalk Active
button, and reboot your Macintosh.  Rebooting your Macintosh is
necessary to establish the link between your netstation and the
server.  By failing to reboot, the network name will not
appear in the "Choose a network"   list.
User  2-6 If the Login box  in the Chooser remains dim during
any log in attempts, the RAM cache on the Control Panel may be
set too high.  For example, with a Macintosh Plus a RAM cache
greater than 256K could cause this to occur.  To lower the RAM
cache;  close the Chooser, select the Control Panel under the Apple
menu, lower the RAM cache and close the Control Panel, open the
Chooser again, and login to the network.

User 2-7 If a large number of domains exist on your network, not
all of them will be displayed in the Login box.  To log in as a user
in a    domain that is not displayed, enter your user name and domain
in the Name box using a colon to separate them.  For example, Jeff
Mason:HQ.

User 2-18 The 3+ Prep file created to automatically login users and
link folders and printers upon bootup only works  on the
AppleTalk network on which it was created.  To create or change
the startup configuration, open the Chooser, log into the network,
link to the desired shared folders or printers, click Status in the
3+ Network Window, click Save as Startup, and click OK.  To delete the
startup configuration, open the System Folder and drag the 3+ Prep
file into the trash can.  To disable 3+ Prep when rebooting your
Macintosh, simply hold the mouse button down after the Welcome to
Macintosh is displayed.

User  2-23 Users are reminded to choose Shutdown before
turning off their Macintosh netstations.  The recommended procedure is
to save your latest work, quit your application, and choose Shutdown
from the Special menu in the Finder.  Shutdown unlinks all network
objects, logs you out of the network, and ejects any diskettes in your
netstation's drives.

User 4-1 If for any reason, you decide to rebuild your desktop on
the network (by holding down the Command and Option keys when starting
up or returning to the Finder), only do so from the Home Folder level
or another first level shared directory (such as 3Plus or APPS if
shared by the server-user).

User  4-1 Switch launching to 3+ shared folders is not supported
in this release.  Attempts to switch launch (while holding down the
Command and Option keys and double clicking on the Finder icon in a
system folder) to a shared folder will be ignored by 3+ for
Macintosh.  Putting a System or Finder on a shared folder will not
cause switch launching to occur automatically (as it does on hard disk
drives).  The ability to switch launch will be included in a later
release of this product.

User 4-14 Macintosh netstation users linked to shared folders with
Write/Create access rights can copy files to the shared folder, but
not see them.  IBM PC or compatible netstation users can use the
DIR command to see the names of all files in a directory with
Write/Create
access rights, but cannot read them.

Versions of MacTerminal prior to 2.0 are not supported
in this release of the product.

User App.  Status message "<network server
name:domain:organization>   A is not responding...Retrying .  Press
and  . to cancel ".  An example of a network server is
Marketing:HQ:Fisher.  This message appears when the server fails to
respond to requests, and informs you that your Macintosh netstation is
repeating a request to the server that has not been answered.  By
taking no action, the retry will continue indefinitely. Press and a .
(period) to end the retry.  This status message has no ID or Type
designation because it reflects status rather than any error
condition.  When you cancel the retry, all connections to the server
from your netstation are lost.  You must reboot your Macintosh
netstation and login again.

.H1;File System Information
User  4-7 A Macintosh user will be unable to create or move a
folder into another folder if the full pathname of any folder or file
exceeds a 94 character pathname limit.  This still permits a fairly
deep folder environment (approximately 9 levels deep with large
folder names).  If shorter names are used, still greater depth is
possible (subsequent renaming may be prevented if the 94 character
pathname limit is exceeded).

If you share directories that are deep within an existing
folder hierarchy, the maximum depth of any newly shared folder is
restricted because of the pathname length limit (pathnames from the
root directory).  The 94 character pathname limit is further
explained under the IBM PC Netstation Information  section of the
release notes.

User 4-13 Shared folders, or folders that contain shared folders,
should not be renamed or moved.  Users linking to a shared folder that
has been renamed or moved will be unable to access the files and
may receive an error message.  If you want to change the name of a
shared folder, unshare the folder first, then reshare it with a new
name.  If you want to move a shared folder to another location,
unshare it first, move the folder, then reshare it.

A folder can be assigned more than one shared folder
name.  It is not advisable, however, for a user to link through two
different shared folder names to the same folder.  Doing so may
lead to the accidental deletion of files.  Both shared folder names
actually represent the same information on the server's disk.
When attempting to copy a file from one to the other,
data will be lost. The Finder will present a message asking if the
user wants to replace the existing file in the destination folder with
the new one.  Since these two files are actually one with the
same name, the Finder is trying to replace that file with itself.
When the user clicks Yes, the Finder will delete the file
from the destination folder before it attempts to copy the file from
the source folder.  As a result the file is mistakenly deleted before
it can be copied, and its data will be lost.

.H1;Application Compatibility Information
User  1-6 The developer's tool ResEdit (version 1.0) is limited to
work only on files in the root level (the window that opens when you
double-click on the shared folder icon on the desktop) of 3+shared
folders.  To use ResEdit on a file outside of the root level, first
move the file to the root level.

User 2-16 To use AppleShare and 3+ for Macintosh from the same
diskette or hard disk, start with an AppleShare boot diskette (because
AppleShare modifies the System file).  Copy 3+ File, 3+Print, and 3+
Icon Giver from the System Folder of your 3+ShareUser for Macintosh
diskette to the System Folder of your AppleShare diskette.

User 3-2 To print using the Cricket Draw application, you must
rename the 3+ Print file in your system folder to LaserWriter.
Cricket Draw only sends files in a PostScript format when the 3+ Print
file is named LaserWriter.  Renaming 3+ Print will not affect any
other 3+ for Macintosh network operations.  The Chooser will still
show the 3+ Print icon, but it will be named LaserWriter.

User  3-6 For best results with PageMaker 2.0, use the Apple
LaserWriter driver.  Permanently downloading the Aldus Prep file
causes the LaserWriter to run out of memory very quickly.  To download
Aldus Prep temporarily, open the PageMaker Print dialog box, hold down
the [Option] key, and click Print.  Click the Make Aldus Prep
permanent checkbox to remove the X.  Then send the
document to be printed.  For complete information on this PageMaker
option, see "Using PostScript Options" in your PageMaker manual.  Only
PageMaker versions 2.0 and later are supported in 3+ for Macintosh.

User 4-16 Occcasionally an application may generate a system error
with-out breaking links to shared folders.  The server will try to
reestablish a link to the shared folder or folders for
approximately two minutes.  After that time, rebooting and logging
into the network from the same netstation should allow you to link to
the shared folder again.

If an error message is displayed when trying to link to a
shared folder after logging into the network from the same netstation,
ask your Network Administrator to use the Unlink User function of the
Admin application to unlink you from the server.

User 4-18, Only Excel versions 1.04 and later (versions designed
to use 4-19 with AppleShare) are supported.

Switcher will not be supported in this release of the
product.

.H1;IBM PC Netstation Information

IBM PC or compatible netstation users should
exercise caution B in copying Macintosh files.  If a file is created
on a Macintosh netstation and an IBM PC or compatible netstation user
attempts to copy it, the file's resource fork will (if present) not be
copied and the Macintosh attributes will not be carried forward.
Without this information the file will not be accessible.  See
Appendix B of the 3+ for Macintosh Supplement for complete information
on the Macintosh data and resource forks (Appendix B covers the
Macintosh service parameters;  Macintosh threads, MS-DOS data
fork extension, MS-DOS resource fork extension, and MS-DOS file
extension mappings).  User App.  Because of the way pathnames to
server directories and files are D managed in Share (DOS), there is a
limitation on the depth of a folder hierarchy in terms of a maximum
DOS pathname length. The current limit is set at 94 characters and
includes the drive    ID ("c:\x\y" is 6 characters long).  Folders
created on a Macintosh that have names that are not legal DOS names
will always have DOS names 8 characters in length or less.

User App. Renaming of folders will not be permitted if the length of
any D folder or file pathname will result in a violation of this 94
character pathname limit.

IBM PC and compatible netstations users should know that
the file/folder name length of the DOS directory listing being
displayed as 0 (zero) is valid for applications and some types of
documents when doing a DIR listing.  The DOS DIR directory command can
display the file/folder name length as 0 (zero), but users should be
cautioned against deleting this file without  first using the MACDIR
command.  This is due to the differences between the DOS and the
Macintosh File Systems.  A zero length file may be an empty data fork
for a Macintosh file.  Use the command to verify the full file/folder
name.

MACDIR will display a directory somewhat similar to a
DOS directory listing, but with Macintosh file system information
added.  The full name of the file/folder within the Macintosh file
system can consist of up to 31 characters, some of which are
illegal in DOS names, such as spaces.  File naming, therefore, will
not necessarily look the same.  If you are unsure about the status
of a file seen in a DOS DIR listing, use the MACDIR listing before
deleting anything.  Refer to the 3+ for Macintosh Installation
Supplement, Table B-1, for an example.

.H1;Multiple Server Support
In this release, Macintosh netstations are not able to use
3+Route to access shared folders and printers on remote
servers via modem and telephone line connections.  3+Route can
continue to be used by IBM PC and compatible netstation users in this
manner and will continue to support the sending and receiving of
messages via 3+Mail.  Full 3+Route support for Macintosh netstation
users will be included in a future release.

However, you can configure your network to support
multiple servers by connecting the servers with Ethernet cabling.
Each server on the network can have an Ethernet segment and
an AppleTalk segment attached to it.  Macintosh netstation
users can then access shared folders or shared printers on any server
on the network.
