WELCOME TO PARADOX FOR WINDOWS 4.5
----------------------------------
This file contains important, late-breaking information
about Paradox, including revisions to the documentation.
This README is one of five online files included with
Paradox. You'll find additional information in these files:
File Contains
---- --------
UPGRADE.TXT New features of the interactive Paradox
product.
NEWPAL.DB A Paradox table containing new and enhanced
ObjectPAL methods, procedures, and
properties. This table also contains SQL-
specific ObjectPAL methods. See the "Using
NEWPAL.DB" section of UPGRADE.TXT for details
on working with this table.
HELPME.TXT Tips and techniques for working with Paradox.
SETTINGS.TXT An explanation of .INI file settings.
UPGRADE, HELPME, and README, are included as icons in your
Paradox for Windows 4.5 Windows group. To open SETTINGS, use
the text editor of your choice.
TABLE OF CONTENTS
-----------------
1. Installation Information
2. Documentation Errors
3. Deleting Optional Software
4. TUTILITY Notes
5. QuickStart Labels Upgrade
1. INSTALLATION INFORMATION
---------------------------
- If you install Paradox on a machine that has a VGA
driver, but is using a monochrome display, the check
boxes on the Installation dialog box do not paint
correctly. You can assume that all check boxes are
checked by default.
- If you install Paradox for Windows 4.5 as a part of the
Borland Office suite, you can disregard the CAUTION
statements on pages 2 and 33 of the Borland Office
Getting Started booklet.
- If, during the installation process, the Install program
attempts to overwrite a file that has the DOS Read-Only
attribute, Paradox returns you to the Installation dialog
box without completing the installation. You must remove
the Read-Only attribute before attempting to install
again.
2. DOCUMENTATION ERRORS
-----------------------
- The Paradox for Windows printed documentation does not
reflect new features and changes in Paradox. See the
UPGRADE.TXT and NEWPAL.DB files for details on new or
enhanced features.
"Getting Started"
-----------------
- You must run DOS SHARE if you want to use multiple
instances of Paradox or ODAPI clients (such as the
Workgroup Desktop or the Database Desktop included with
Quattro Pro for Windows.) If you do not run SHARE in this
situation, the second instance will not load.
The SHARE.EXE command (in either your AUTOEXEC.BAT or
your CONFIG.SYS) should include these optional
parameters:
SHARE /F:4096 /L:40
The /F parameter allocates file space for the DOS storage
area used to record file-sharing information. The default
value is 2048. The /L parameter sets the number of files
that can be locked at one time. The default value is 20.
"User's Guide"
--------------
- The field _Invariant Field ID in the STRUCT.DB table is
used internally by Paradox to identify fields for use in
associated design documents.
- When you export data to or import data from an ASCII
file, your date, numeric, and currency fields use the
settings from your Windows Control Panel.
- If a Windows file association already exists for a .DBF
or .QBE file, Paradox will overwrite it during
installation.
- Under certain conditions in a multiuser environment,
forms bound to unkeyed (unindexed) tables may lose track
of the current record during a lengthy operation. You can
avoid this situation entirely by using keyed tables.
- Page 57: The paragraph describing the write lock states
"Other users can place a read lock on a table that you
have a write lock on." It should state "Other users can
place an open lock on a table that you have a write lock
on."
- When designing a graph in the Report Design window, the
Data Type option is not available from the Define Graph
dialog box.
"ObjectPAL Reference"
---------------------
- AnyType:unAssign() does not return a value. The correct
syntax is unAssign().
3. DELETING OPTIONAL SOFTWARE
-----------------------------
After installing and becoming familiar with Paradox, you
might decide to delete some of the optional software
components (such as sample files). The following table shows
what files you can delete and where they are located. This
table assumes you accepted the default locations when you
installed Paradox.

4. TUTILITY NOTES
-----------------
TUTILITY checks a Paradox table for damage and rebuilds it
if necessary. Paradox tables can be damaged by power
failures, hardware failures, bad network cards or
connections, removing a floppy disk that Paradox is
accessing, or rebooting the system while Paradox is active
in memory. You should always make regular backups of your
important data.
To start TUTILITY, type TUTILITY at the DOS prompt, then
press [Enter]. If you installed Paradox in the PDOXWIN
directory, you can also start TUTILITY from its icon in the
Paradox for Windows group. If you installed to a different
directory, you have to edit TUTILITY.PIF before you can
start TUTILITY from its icon.
Additional instructions and a description of program options
are provided in the TUTILITY.DOC file. Online help is also
available when you run the program. Command-line help is
available by typing TUTILITY -help.
5. QUICKSTART LABELS UPGRADE
-----------------------------
If you purchased Borland's QuickStart Labels package, for
use with Paradox for Windows 1.0, please call Borland
Customer Support at (408) 461-9000 for an upgrade.
