1. OPTIMIZING DISK SPACE
-------------------------

NOTE:  You may want to delete some optional software
       components (such as the Sample files) after you've
       become familiar with Paradox. Refer to the "Deleting
       Optional Software section of the README file for
       information on how to delete optional software
       safely.

Q. There are a number of .CFG files in my ODAPI directory.
   What are they and how are they used?

A. When you install Paradox, the INSTALL program examines
   the Country settings in the Windows Control Panel and
   configures ODAPI to appropriate data format conventions,
   using the .CFG files you see in your ODAPI directory.

   The following list describes these configuration files
   and the country supported by each file. In some cases,
   multiple .CFG files are available for a specific country;
   when this happens, the language supported by the .CFG
   file is given in parentheses.

     AUSEN437.CFG     Australia (437)
     AUSEN850.CFG     Australia (850)
     AUTDE437.CFG     Austria (437)
     AUTDE850.CFG     Austria (850)
     BELFR437.CFG     Belgium (French, 437)
     BELFR850.CFG     Belgium (French, 850)
     BELNL437.CFG     Belgium (Dutch, 437)
     BELNL850.CFG     Belgium (Dutch, 850)
     BRAPT850.CFG     Brazil
     CANFR850.CFG     Canada (French, 850)
     CANFR863.CFG     Canada (French, 863)
     CHEDE437.CFG     Switzerland (German, 437)
     CHEDE850.CFG     Switzerland (German, 850)
     CHEFR437.CFG     Switzerland (French, 437)
     CHEFR850.CFG     Switzerland (French, 850)
     CHEIT437.CFG     Switzerland (Italian, 437)
     CHEIT850.CFG     Switzerland (Italian, 850)
     DEUDE437.CFG     Germany (437)
     DEUDE850.CFG     Germany (850)
     DNKDA865.CFG     Denmark
     ESPES437.CFG     Spain (437)
     ESPES850.CFG     Spain (850)
     FINFI437.CFG     Finland
     FRAFR437.CFG     France (437)
     FRAFR850.CFG     France (850)
     GBREN437.CFG     Canada (English, 437)
     GBREN437.CFG     Ireland (437)
     GBREN437.CFG     New Zealand (437)
     GBREN437.CFG     United Kingdom (437)
     GBREN850.CFG     Canada (English, 850)
     GBREN850.CFG     Ireland (850)
     GBREN850.CFG     New Zealand (850)
     GBREN850.CFG     United Kingdom (850)
     ISLIS861.CFG     Iceland
     ITAIT437.CFG     Italy (437)
     ITAIT850.CFG     Italy (850)
     KOREN437.CFG     South Korea
     MEXES437.CFG     Mexico (437)
     MEXES850.CFG     Mexico (850)
     NLDNL437.CFG     Netherlands (437)
     NLDNL850.CFG     Netherlands (850)
     NORNO865.CFG     Norway
     PRTPT850.CFG     Portugal (850)
     PRTPT860.CFG     Portugal (860)
     SWESV437.CFG     Sweden (437)
     SWESV850.CFG     Sweden (850)
     TWNEN437.CFG     Taiwan
     USAEN437.CFG     United States (437)
     USAEN850.CFG     United States (850)


   File names for country configuration files describe the
   country, language, and OEM code page the configuration
   file is designed to support. For example, USAEN437
   supports the English language conventions used in the
   United States and is intended for use with OEM code page
   437.
  
   - The first three characters of the file name indicate
     the country supported by the configuration file and
     correspond to ISO abbreviations. For example, file
     names starting with CHE support Switzerland.

   - The next two characters indicate the language
     supported by the configuration file and correspond to
     ISO abbreviations. For example, file names containing
     ES support Spanish.

   - The last three characters indicate the OEM code page
     supported by the configuration file. For example, file
     names ending with 437 require OEM code page 437.

     NOTE: If you have a .CFG file with a file name that
           doesn't match this format, it is used by Paradox
           (or ODAPI) and should not be deleted.


Q. Can I safely delete the configuration files listed above?

A. If you will not be changing the Country setting in the
   Windows Control Panel, you can delete these .CFG files.
   However, if you plan to change Control Panel settings,
   you can delete only those files you will not need.


Q. I've changed the Country or International settings in the
   Windows Control Panel. According to "Getting Started," I
   need to configure ODAPI to match the new Control Panel
   settings. How do I do this?

A. There are three ways you can do this:

   - Use the ODAPI Configuration Utility.
     - Choose System|Formats|Date to change the date
       settings.
     - Choose System|Formats|Time to change the time
       settings.
     - Choose System|Formats|Number to change the number
       settings.

   - Use the DOS COPY command to replace ODAPI.CFG with the
     appropriate country configuration file. For example,
     if ODAPI is currently configured for U.S. data
     conventions and you want to use your data displayed
     with United Kingdom conventions, use the following
     command:

     COPY GBREN473.CFG ODAPI.CFG

     CAUTION: If you have customized ODAPI.CFG in any way,
               this process overwrites your changes. For
               example, if you've defined (and saved)
               directory aliases, they will be lost.
               (Aliases are saved in ODAPI.CFG.)

   - Reinstall Paradox. The Paradox Installation program
     automatically chooses the country configuration file
     appropriate for the country defined in the Windows
     Control Panel.


Q. I have .CFG files that are not in the above list of
   country configuration files. What are they?

A. .CFG files not listed above fall into two categories:
   files that are not country configuration files (like
   ODAPI.CFG or TUTILITY.CFG) or country configuration files
   that have been added since this document was last
   updated. To see if an unlisted .CFG file may be a new
   country configuration file, look at its file name.


2. COMPATIBILITY WITH PARADOX DOS 4.0 or 4.5
--------------------------------------------

Q. How do I run a Paradox DOS 4.0 or 4.5 script from Paradox
   for Windows?

A. The following procedure lets you create an association in
   Windows so you can run a Paradox DOS 4.0 or 4.5 script:

   1)In the Windows File Manager, select the directory
     containing Paradox DOS 4.0 or 4.5 and choose
     File|Associate.
  
   2)In the Files With Extension text box, type .SC.
  
   3)Use Browse to choose PDOXDOS.PIF from the directory
     containing Paradox DOS 4.0 or 4.5 (it appears in the
     Associate With text box) and choose OK.

   After creating this association, you can add a Paradox
   DOS 4.0 or 4.5 script icon to the Folder window in
   Paradox. (Click the Add Item SpeedBar button and choose
   the <Files> type in the Select File dialog. All files,
   including scripts, in the directory appear in the file
   list.) Once you've added the script's icon to the Folder
   window, double-click it to launch Paradox DOS 4.0 or 4.5
   and play the script. (Paradox DOS 4.0 or 4.5 must be on
   your path.) If you can launch Paradox DOS 4.0 or 4.5 but
   can't play the script, modify the .PIF file (use the
   Windows PIF Editor) to set the startup directory to the
   location of the script you want to play.

   For more information about .PIF files or file
   association, see your Windows documentation.


Q. Will Paradox convert my Paradox 3.5 (or earlier) tables
   to Paradox tables?

A. Only if you restructure these tables and add Paradox for
   Windows (or Paradox DOS 4.0 or 4.5) features, such as
   memo or BLOB fields, secondary indexes, or referential
   integrity. To convert a Paradox 3.5 table to a Paradox
   for Windows table, restructure it in Paradox and add one
   of the features described above. (You do not have to
   convert Paradox 3.5 tables to use them with Paradox.)


Q. I have a table that I converted from Paradox 3.5 to
   Paradox DOS 4.0 or 4.5. This table has more than 64
   validity checks. Can I open it in Paradox?

A. Yes, but you cannot use Restructure or Info Structure
   from Paradox on this table. If you attempt to, you'll see
   the message "Not enough memory."


Q. How can I convert a Paradox (or Paradox DOS 4.0 or 4.5)
   table to a Paradox 3.5 table?

A. The safest way to do this is to create a new Paradox 3.5
   table and borrow the structure, primary key, validity
   checks, and lookup table properties of the Paradox table.
   After saving the Paradox 3.5 table, use
   File|Utilities|Add (or an INSERT query) to copy the data
   from the Paradox table into the Paradox 3.5 table.

   NOTE: If you add Paradox (or Paradox DOS 4.0 or 4.5)
         specific features (referential integrity, memo or
         BLOB fields, or secondary indexes) to the Paradox
         3.5 table, it will be converted to a Paradox table
         when saved.


Q. In DOS Paradox, forms and reports are part of a table's
   "family" of files and must be copied with the table when
   using the DOS COPY command. Is this true in Paradox?

A. No, design documents are not copied when you copy a
   table. For more information, see Chapter 2 in the Paradox
   for Windows "User's Guide."


3. COMPATIBILITY WITH dBASE
---------------------------

Q  What comparison operators are allowed in expression
   indexes on dBASE tables?

A. You can use the =, <=, and >= comparison operators in
   expression indexes; =< and => are not supported. See your
   dBASE documentation for syntax.


Q. What functions are allowed in expression indexes on dBASE
   tables?

A. The following dBASE IV functions are supported. See your
   dBASE documentation for syntax.

   ABS              DTOR           LOG10           RTRIM
   ACOS             DTOS           LOWER           SIGN
   ASC              DTOS           LTRIM           SIN
   ASIN             EXP            MAX             SPACE
   AT               FIXED          MIN             SQRT
   ATAN             FLOAT          MOD             STR
   ATN2             FLOOR          MONTH           STUFF
   CEILING          FV             PAYMENT         SUBSTR
   CHR              IIF            PI              TAN
   COS              INT            PV              TRANSFORM
   CTOD             ISALPHA        RAT             TRIM
   DAY              ISLOWER        RAND            UPPER
   DIFFERENCE       ISUPPER        REPLICATE       VAL
   DIV              LEFT           RIGHT           YEAR
   DOW              LEN            ROUND
   DTOC             LOG            RTOD


Q. Can I use Paradox to open a dBASE table that has a dBASE
   III style memo field and a production index?

A. No, your dBASE table can use either a dBASE III style
   memo field or a production index, but not both. When you
   attempt to open the table, you'll see the "Corrupt
   table/index header" message. You should restructure the
   dBASE table to change the memo type.


4. DEBUGGING OBJECTPAL CODE
---------------------------

Q. How do I debug ObjectPAL code on a form or library that
   is called from another form or library?

A. You must set a breakpoint both in the ObjectPAL code that
   calls the second form or library and in the code on the
   second form or library. While single-stepping through the
   code that calls the second form or library, step into the
   method or procedure on the second form or library.


5. REFERENTIAL INTEGRITY
-------------------------

Q. Why do I see messages such as "Detail table exists" and
   "Table open operation failed" on tables with referential
   integrity relationships?

A. Referential integrity lets you define and enforce strict
   rules about how the data in two or more tables is
   related. In return, you give up some flexibility in
   renaming, moving, and modifying those tables.

   Referential integrity is more important for critical-
   application tables than for tables that may change in
   structure frequently. Determine the name, location,
   structure, and contents of all tables involved in the
   referential integrity relationships before you define
   referential integrity links among them. To copy or move
   the tables after defining referential integrity, follow
   these rules:

   - Within a directory, copy tables using
     File|Utilities|Copy. Paradox keeps the referential
     integrity relationship for the copy of the child table
     (since two child tables can look to the same parent
     table) but deletes it from the copy of the parent
     table (since a single field in a child can't look to
     two parents).
  
   - Across directories, use either File|Utilities|Copy or
     the DOS COPY command, depending on whether you need to
     retain referential integrity:

     File|Utilities|Copy deletes the referential integrity
     relationship when you copy across directories. You can
     use Restructure to rebuild it.

     DOS COPY retains the same referential integrity
     relationship. If you use DOS COPY, be sure to copy all
     files associated with a table's file name. For
     example, to copy CUSTOMER.DB to the root directory of
     your local drive, you would use
  
     COPY CUSTOMER.* C:\.
  
   - To distribute an application or move it to a network
     directory, copy the tables using DOS. To retain
     referential integrity, make sure you copy all files
     associated with a table's file name.
  

6. EDITING IN MULTI-TABLE FORMS
-------------------------------

Q. My data model includes a table with a 1-to-1 link to the
   master table. In Edit mode, I can modify fields from the
   master table, but not fields from the 1-to-1 linked
   detail. Why?

A. Often, a 1-to-1 detail table acts as a lookup table. For
   example, you might have a two-character State field in
   the master table, and use a lookup table to the
   corresponding full state name for each two-character
   abbreviation. In this case, you wouldn't want anyone to
   change a value in the state name table (thinking that
   they were changing just a single record in the master).
   Instead, you might want to use another form, without the
   lookup table, for address changes. To be safe, Paradox
   assumes that 1-to-1 detail tables are lookups and makes
   them read-only by default.

   NOTE: If you inspect the detail table in the data model
         diagram shown in the Data Model dialog box, you'll
         see that its Read-Only property is checked by
         default. If you want to edit the detail table in
         the form, uncheck Read-Only in the Data Model
         dialog box.


7. REPORT TECHNIQUES
--------------------

Q. I replaced the table name in the default header of a
   report with a text object. The text object is centered in
   the report design, but it's too far to the right when the
   report prints. Why?

A. When you run the report, the date field to the left of
   the header grows, pushing the text object to the right.
   To fix this, check the text object's Run Time|Pin
   Horizontal property. This keeps the text object from
   moving when you run (print or preview) the report.

   The easiest way to center text is to center the text
   object using the ruler, then center the text within the
   text object. For example, you can place a text object
   that extends from the 2" mark to the 6.5" mark on an 8.5"
   page. Type the text you want in the text object, inspect
   the text object and check Alignment|Center.


Q. How can I sort records in a tabular report without
   creating separate tables each time the sorted value
   changes?

A. A group band on a field always produces a separate group
   for each distinct value in that field, so you often can't
   get the look you want by using a group band to sort
   within a group.

   Instead, define a query that selects just the fields you
   want to report on, define the sort order for the answer
   using Properties|Answer Table|Sort, and bind the report
   to the saved query.


Q. Can I place a crosstab object in a report?

A. No, but you can probably get the desired effect by
   designing a form for the printer. Use the Design For
   panel of the Page Layout dialog box, then choose the page
   size and margins you want to use. After choosing OK,
   place and define the crosstab object. To print the
   results, open the form in a Form window and choose
   File|Print.


Q. I can't always control the orientation used by my printed
   reports? What should I be doing?

A. If you create a new report, you must explicitly specify
   either landscape or portrait orientation in the Page
   Layout dialog box; otherwise, your report will print in
   the orientation used by the previous report.


Q. How do I achieve the effect of a group band nested in a
   group-by range band?

A. In Paradox, Group By Range groups all records in the
   specified range together for the purpose of determining
   group breaks, summaries, headers, and footers. It does
   not have the effect of sorting by range. This means you
   can't place another group band within a Group By Range
   band; the records in the group must be ordered in
   sequence, and a nested group band only affects the
   sorting of exact matches within the outer group.

   One workaround you can use is to

   1)Add a field or fields to the table to hold the range
     information.
   2)Write and run a simple script to fill the new
     field(s).
   3)Base the report grouping on the new field(s). You can
     then nest another group within this group.


8. ODAPI PERFORMANCE
--------------------

Q. How can I improve performance?

A. For database-intensive operations (such as queries,
   utilities, and navigation in very large tables) use the
   ODAPI Configuration Utility to set the maximum buffer
   size to 80% of physical memory or physical memory minus 2
   MB, whichever is greater. This will improve ODAPI
   performance, but may slow down other Windows tasks,
   including non-database operations in Paradox itself.

   You should also avoid placing tables on the network if
   they are not shared.

   If you have LocalShare set to On and are not currently
   sharing tables with non-ODAPI hosted applications on your
   local drive, turn LocalShare off.


9. DDE AND OLE
--------------

Q. Why can't I use Paradox as a DDE server?

A. Because your Paradox system directory is not included in
   your DOS path. To fix this, edit your DOS PATH before
   starting Windows. For more information about your PATH,
   consult your DOS and Windows documentation.


10. NETWORKS
------------

Q. Why do some people on my network have valid user names
   while others have blank user names?

A. You won't have a user name (and File|Multiuser|User Name
   will display "Not on network") if you don't have a
   network driver installed in Windows. Paradox will still
   work on a network, but you don't get network-specific
   benefits, such as performance optimizations and user
   names displayed on lock conflicts.


Q. I can start Paradox, but I can't use Paradox tables on
   the network. Why not?

A. You probably haven't identified the location of your
   network control file. Run the ODAPI Configuration Utility
   and specify the location of this file. (Ask your network
   administrator where the network control file is.)


Q. Why can't I access a table in my working directory?

A. If your working directory is on a network, another
   network user may have identified it as their private
   directory, or a Paradox DOS 4.0 or 4.5 user may have
   locked the directory.


11. AUTOMATIC WINDOW SIZING
---------------------------

Q. Why do all child windows become maximized when I maximize
   one child window? Why do all child windows become
   restored when I restore one?

A. This is how Windows Multiple Document Interface (MDI)
   manages child windows.


12. SAMPLE FILE LOCATIONS
-------------------------

Q. Where are the three subdirectories SAMPLE, DIVEPLAN, and
   EXAMPLES located?  What do they contain?

A. These directories contain sample files that are referred
   to in your Paradox for Windows documentation. If you
   accept the installation defaults, these directories are
   located in subdirectories of your Paradox system
   directory.

   - SAMPLE contains tables and forms used in examples in
     "Getting Started" and the "User's Guide."
   
   - DIVEPLAN contains an ObjectPAL sample application, a
     trip planner for scuba divers.
   
   - EXAMPLES contains small ObjectPAL code examples, which
     are referred to in the ObjectPAL documentation. If you
     are a user of the Workgroup Edition, the EXAMPLES
     directory also contains the SQL Tools that help you
     manage remote data more easily.


13. SETTING FILTERS ON REPORTS
------------------------------

Q. When I use the Table window to view a table that has a
   filter set on it (using the Order/Range dialog box), and
   then click the Quick Report or Print SpeedBar button, why
   do I get the full table in the report?

A. Because reports don't support filters (ranges) set from
   the Order/Range dialog box. If you want a report on a
   specific range of data, create a query on the table to
   select the records you want to print, then create the
   report on the saved query.


14. DESIGNING FORMS
-------------------

Q. What if there's not enough room on my screen for my
   form's layout?

A. This problem sometimes occurs when you choose OK from the
   Data Model dialog box. If you get an error message, use
   Select Fields and specify fewer fields or use Page Layout
   and specify a larger page.

   You may also have encountered a problem with your display
   driver software. If the previous suggestions don't work,
   try reinstalling your display driver. Consult your
   Windows documentation and your display driver
   documentation for information about installing display
   drivers.


Q. Sometimes the default tab order in a form isn't what I
   want. How do I change it?

A. To make sure the tab order moves to each of several
   adjacent fields before moving to the next group of
   adjacent fields, multiselect the fields, inspect them,
   and choose Design|Group.

   For more sophisticated ways to control tab order, you can
   use ObjectPAL.


Q. Why doesn't my crosstab object update when the data
   changes?

A. If you create a crosstab, then edit the table on which
   the crosstab is defined, the crosstab is automatically
   updated only if you edit the table from the same form
   that contains the crosstab.

   If you edit the table from anywhere else, you must
   refresh the crosstab by pressing CTRL+F3 (or reopening
   the form).

   NOTE: Using Order/Range on a table causes an automatic
         refresh of the crosstab even if you set the
         Order/Range from outside the crosstab's form.


15. SCREEN DISPLAY
------------------

Q. What Windows Control Panel Color Schemes appear best in
   Paradox?

A. The following Color Schemes work best with Paradox:

   Arizona         Fluorescent           Patchwork
   Ocean           Hot Dog Stand         Rugby
   Bordeaux        Monochrome            Valentine
   Cinnamon        LCD Reversed - Light
   Emerald City    Black Leather Jacket


Q. Why can't I see the text within text objects on some of
   my forms?

A. If a form has been designed for a printer, and you have
   selected a printer driver that does not support a font
   used in your form, you will not be able to see the text.
   Use a different printer that supports the fonts used in
   your form.

   If you do not want to print the form, you can redesign it
   for the screen. To redesign the form, open it in the Form
   Design window, choose Form|Page|Layout, and then choose
   Screen in the Design For panel.


Q. Why can't I see any text in Paradox?

A. This situation results from your Windows Control Panel
   settings. When you have installed a DeskJet 500C or a
   printer which cannot accept downloaded fonts, set your
   Windows Control Panel as follows:

   - "Enable TrueType Fonts" should be checked.
   
   - "Show Only TrueType Fonts in Applications" should be
     unchecked.


Q. Why do I see very small fonts?

A. If you choose the Generic/Text Only printer you may have
   this problem. You can change the font to Roman 10cpi.
   Windows allows you to select fonts that won't work with
   the printer, but will work onscreen. You should not use
   the Generic/Text Only printer.


Q. Why don't I see the complete contents of my memo and
   formatted memo fields in my tables and forms?

A. By default, the memo field's Complete Display property is
   unchecked. This makes screen refreshes faster. To see a
   whole memo, you can move to that field. (In a Table
   window, you might need to enter field view.) To see all
   memos at all times, you can inspect the field and check
   Complete Display.


Q. I have a form that hides the SpeedBar. When I close the
   Form Window (or change it to a Design window), the
   SpeedBar stays hidden. What should I do to display the
   SpeedBar?

A. To display the SpeedBar, choose Properties|Desktop, then
   choose OK.


16. FOLDER TECHNIQUES
---------------------

Q. Can I use different folders for a single directory?

A. Yes, by indicating an alternate PDOXWORK.INI file when
   you start Paradox. This is useful when different users
   need the same files for different tasks. For more
   information, see Chapter 14 of your Paradox for Windows
   "Getting Started."


Q. Where are the contents of a folder stored?

A. In the [Windows] section of PDOXWORK.INI. For more
   information, see SETTINGS.TXT in your Paradox system
   directory.


Q. I have trouble opening files when I use an alternate
   folder. Why?

A. Paradox can't find the files listed in the [Windows]
   section of your alternate PDOXWORK.INI file. For best
   results when using an alternate PDOXWORK.INI, be sure the
   file names listed in the [Windows] section include full
   directory paths or saved alias definitions. For example,
   if the alternate folder contains an icon for the sample
   CUSTOMER table, make sure the [Windows] section contains
   a reference for C:\PDOXWIN\SAMPLE\CUSTOMER.DB.


Q. Can I use relative directory paths in a folder?

A. Yes, if the relative directory path is available to the
   working directory in which the folder is used.


Q. Can I prevent Paradox from changing the contents of a
   folder?

A. Yes, by adding the -e option to the FLAGS= line in the
   [PDOXWIN] section of WIN.INI. For more information, see
   the "Command-Line Options" section of the UPGRADE.TXT
   file (located in your Paradox system directory).


17. TROUBLESHOOTING
-------------------

Q. What do the messages "Could not open," "Table is busy,"
   and "File is busy" mean?

A. A file you tried to access is already open in a Desktop
   window or it is locked by another user or application.
   For example, if you received one of these messages while
   trying to run a query, a Table window may contain an
   Answer table from a different query. (Paradox can reuse
   an Answer table window from a single query, but not the
   Answer table window from a different query.)

   To avoide these messages, close windows containing the
   file you tried to open, or coordinate access to a file
   that is used by other users or applications. If you are
   sharing files with non-ODAPI hosted applications on your
   local drive, make sure you used the /F and /L parameters
   when loading SHARE.EXE. For more information, see
   "Getting Started" in the "Documentation Errors" section
   of README.TXT.


Q. How does Paradox respond when an attempt to read from a
   floppy drive fails?

A. When you first access a table on a floppy drive, Paradox
   checks to see if the drive is ready; if it isn't, Paradox
   displays the message "Could not access drive".

   If you try to access the drive later and it is not ready,
   Windows displays a system error such as "Cannot read from
   drive A:", and asks you to Retry or Cancel the operation.
   If you resolve the problem (for example, by making the
   drive ready) and select Retry, Paradox continues to use
   the table. If you select Cancel, Paradox stops using the
   table and displays the message "Access to table disabled
   because of previous error".

   At this point, any operation that causes Paradox to
   repaint the window containing the table will make the
   table appear to be empty. When this happens, close the
   window and open it again after fixing the problem that
   caused the system error. If you are editing and have an
   unposted change to a record, you must use Edit|Undo to
   discard the record before you can leave Edit mode (just
   as you would with any unpostable record).


Q. What is the recommended procedure for working with
   records in a multi-user environment?

A. The recommended procedure for working in a multi-user
   environment is the following:

   1)Move to the record.
   
   2)Lock the record, even if you don't intend to edit it.
   
   3)Check to make sure that the record you locked is the
     record that you wanted to work with.
   
   Remember, in a multi-user environment, other users can
   change the data after you move to a record but before you
   are able to lock it. During this time, changes to any
   record could cause the record you are viewing to move,
   change, or even be deleted. It is recommended that tables
   used in multi-user environments be keyed. When an unkeyed
   table is edited by several users, it is possible that
   Paradox could lose track of record positions.


Q. When using Import/Export, how do I handle data with
   embedded delimiters?

A. If your field delimiter is quotes, each embeded quote
   should be represented in the import file by a double
   quote.
