- TITLE : A Brief Description of New Features in Paradox 3.5
-
-
-
-
- The major changes in the technical upgrade of Paradox ver 3.0 to
- 3.5 are in the areas of memory management, connectivity to SQL
- databases, updates to PAL, changes in the form and report
- generators, and some improvements to the Custom Configuration
- Program.
-
- 1-In the area of memory management the major changes are:
-
- The application of VROOMM (tm) technology into Paradox now allows
- it to run faster while requiring less memory (depending on
- equipment and configuration), thereby leaving more memory for
- your network drivers, your applications, and/or your data.
-
- On an 80286 or 80386 based computer Paradox can be configured to
- run in real mode or protected mode if you have more than 1MB of
- RAM. Real mode is that which simulates the functionality of the
- 8086 computer, (addressing up to 1MB of RAM) and the ability to
- utilize expanded memory only. In real mode Paradox 3.5 can use
- expanded (EMS) and extended RAM as a swap device or disk cache.
- In protected mode Paradox can now utilize your systems' hardware
- to best advantage. Since extended memory does not use a memory
- manager based on 64K pages, its' use is advantageous over
- expanded memory. Paradox 3.5 can load in protected mode if there
- is 1MB or more of extended memory, so that up to 16MB of RAM can
- be addressed for program code, applications, data, scripts and
- variables. With enough memory swapping to disk can be reduced in
- most cases. This also means that Paradox 2.0 version 386 is no
- longer needed. In addition, there are command line parameters
- that will allow you to control the amount of extended and/or
- expanded memory Paradox 3.5 is using, thereby leaving the
- remainder of your memory available for other programs.
-
- If you are operating on a 8088 IBM XT, there will be little or no
- difference in the performance you will see. If you have a 286 or
- 386 and no extended RAM, again you will notice little change. If
- however you have a 286 or 386 and total RAM of more than 2
- megabytes, your applications should run faster. How much faster
- will be determined by a number of different factors. The type of
- work you do and how much RAM you have available for Paradox 3.5
- are the two main determining factors.
-
- 2-A second area which differs from Paradox 3.0 is connectivity.

-
-
- Paradox 3.5 is SQL Link available for when you might need
- connectivity an SQL database. The Paradox SQL-Link is a separate
- package you can add anytime. With the SQL Link Paradox can now
- perform QBE and other data manipulation operations on data stored
- on the following SQL servers without the user first having to
- learn SQL:
-
- -IBM OS/2 Extended Edition v 1.2 Database Manager
- -Oracle Server v6.0
- -Microsoft SQL Server v 1.0 or higher
- -with more SQL database servers to be added in the future.
-
- 3-Improvements to Forms and Reports include:
-
- Now up to 9 tables may be embedded in a single master form (up
- from 5 embedded tables in version 3).
-
- Also, many PAL functions and commands are now available in
- Reports and Forms. Some of these are: ABS, ACOS, CAVERAGE, CSUM,
- CSTD, CMAX, CVAR, DATEVAL, DAY, DOW, EXP, FORMAT, LEN, LOWER,
- MAX, MONTH, NRECORDS, PMT, RAND, ROUND, SQRT, STRVAL, TIME,
- TODAY, UPPER, USERNAME, YEAR.
-
- 4-Changes to Paradox Network Support are:
-
- Paradox now supports 3Com 3Plus Open networks. Additionally,
- Paradox also supports:
-
- -Standard 3Com 3+
- -Novell Netware Versions 2.0A or higher
- -IBM PCLan Version 1.12 or higher
- -AT&T StarGroup for DOS Version 3.1 or higher
- -Banyan Vines version 2.10 or higher
-
- 5-The Custom Configuration Program Has the Following Additions
- and Changes:
-
- Tune: The custom program has a new section called Tune that deals
- with the way Paradox handles the use of Extended and Expanded
- RAM. From within the Tune menu you can optimize the speed with
- which Paradox accesses Protected Mode RAM.

-
-
- Setting colors has a new menu which makes customizing the Paradox
- screens a simpler process.
-
- 6-Some Other Changes To Paradox are:
-
- Import/Export - Now able to Import/Export Quattro Pro Files
-
- Menus - Paradox now uses "incremental menus". If any menu has
- more than one choice with the same starting letter, typing the
- second, third and successive letters of the choice you want will
- select the item with the minimum number of keystrokes. The
- visible list of choices will be limited on-screen as the letters
- are entered.
-
- As usual, earlier versions are upwardly compatible. Table
- objects (data, valchecks, image seatings, etc.) produced in 3.0
- or earlier versions will work in Paradox 3.5 (It is recommended
- that you use {Modify} {Restructure} <F10> {Do-it!} without making
- changes to your tables once in Paradox 3.5).
-
- Microsoft (tm) Windows - Paradox will also run within Enhanced
- mode Windows 3, but only in Real mode. It can use Expanded Ram
- under Windows control as Paradox is XMS compatible. The PIF and
- GRP files are provided for using Paradox under Windows 3.0. See
- the Paradox README.
-
- 7-PAL has been updated in this new release in a number of ways:
-
- Some new PAL commands include:
-
- -CalcDebug which Allows a calculated field to display a blank
- (with OFF option) or display ERROR (with CalcDebug set to ON).
- -SaveTables - Forces table changes out to the disk without
- clearing the workspace, locks and main mode activities.
- -ShowArray, ShowFiles, ShowMenu, ShowTables - The Until and Keyto
- options have been added to the commands above. The Until option
- allows a programmer to set exit keys in a manner similar to the
- WAIT TABLE command. The Keyto option will store the key pressed
- to select from the menu to a variable.
-
- Some of the changed PAL commands are:

-
-
-
- -CopyToArray has been changed to allow insertion of new records
- into detail table.
- -Run NoShell - New option for RUN that will not automatically
- load command.com. This saves memory, and allows DOS error values
- to be passed to Retval when Paradox is entered again.
- -SETSWAP has changed to fit into the totally new memory
- management system.
-
- Some of the new functions are:
-
- -Rmemleft() - This function returns a value representing the
- amount of RAM available in the Code Pool portion of available
- RAM.
- -FormType() - This is a Boolean function that requires a text
- string of a form type (MultiRecord, linked, etc.). The function
- will then return its value based on the type of form currently
- displayed.
- -RecordStatus() - This is a Boolean function that is passed a
- string of a status (new, locked, modified, etc.) It will then
- return true or false based on the status of the current image
- record.
- <Alt-F10> {MiniScript} and {Value} - When using MiniScript or
- Value, the <CTRL-E> key stroke will bring up the last line typed
- in, allowing you to edit the previous line. <CTRL-E> key stroke
- will bring up the last line typed in, allowing you to edit the
- previous line.
