Find out, with the results of this detailed analysis of dynarrays.
On Reports
Has your boss casually asked you to include a Gantt chart in your
next Paradox report? Before you tell her that it can't be done,
read this month's On Reports. All it takes are a handful of PAL
functions, calculated fields, and some know-how from Mr. Todd.
Paradox Tricks & Tips
Maligned, shunned, unappreciated--it's EXECUTE! Despite its bad
press, EXECUTE remains an important command with critical function-
ality. Dr Jensen puts this misunderstood command in perspective.
Project Planning
Coding without planning puts you at the mercy of the end-user.
Instead, plan ahead and develop a Functional Specification
document. Mr D'Amour shows us how to avoid the endless project.
PAL 101
Still a little vague on this z-order thing? Can't get a handle?
You're not alone. In this month's PAL 101 Mr. Bleecher takes the
time to help us sort it all out.
Objects of Interest
Although not an OOP language, Mr Bechmann knows how to make PAL 4.0
behave like one. This month he presents an ambitious button manager-
ButtonMan- and answers the question: What's an Object?
The Competitive Edge
As the Paradox universe expands, the paths of PAL developers are
crossing more often. Here's a plea for Paradox development standards.
Programmers unite! You have nothing to lose but your chains!

Put it on Paper
Paradox for Windows is a highly integrated set of database tools.
Here's a quick guide to creating complex reports.
Customizing Reports
The Paradox for DOS report generator still has a lot to offer. Let
Mr LaTulipe show you how to get the most out of it.
It's a Setup!
Mr San gives an expert's perspective on using Paradox with a
Hewlett-Packard LaserJet. Learn why sometimes reset is not enough.
Export by Report

Braun shows us how to use the report generator to export special files.
HP Laser Labels
Printing labels on a LaserJet is a common task. Here's what to do
when every label counts.
Bar Codes: A Survey
Bar Codes are a big player in today's business environment. Mr
Winston gives us a survey of their use. Guess what? The're easy.
More on Bar Codes
This is all very nice about bar codes, but could you give me a
a Paradox example? Mr Wilkerson provides a PrintBar II solution.
Who needs PRINT?
When all else fails, control the printer the old-fasioned way.
Use the PAL PRINT command.
Learning a NU Trick
Here's one way out of a tight spot. Sometimes it pays to hack.
Paradox Tricks and Tips
Wish you could copy and paste fields in the Paradox for DOS report
generator? Dr Jensen provides a valuable utility and shows you
how he did it.

may not be intuitive, but not without reason. Let Mr Lenaghan
help you get your events straight.
On Queries
Confused by Set queries? Let an expert explain. This month
Mr Ehrmann provides a new twist that has an everyday utility.
OPAL Tech
Every ObjectPAL programmer needs to be able to control menus. Mr
Todd explains that where you control them is as important as how.
Conduit
When it comes to exporting and importing ASCII data, sometimes
Paradox can use a little help. Kallista's Conduit is ready.

Sea of Possibilities
Windows is more than a friendly GUI interface with Solitaire. In
fact it's an ocean of interoperability teeming with shareable
resources. From becalmed to choppy, here's a guide to the varied
interoperable waters.
OLE and DDE
Two of the more intriguing Windows interoperability features are
object linking and embedding and Dynamic Data Exchange. Mr. Fung
offers this brief history and introduction.
For the Record: Part III
For the past two months, Mr K has put together a musical database.
Last month we saw the records and CD's. This month we get to hear
them. It is all made possible by PW's Graphic and OLE capabilities.
Hands-On DDE and OLE
Okay, DDE and OLE sound great. Now show me what they can do. As it
turns out, the possibilities are endless for interactive users and
developers alike. Mr Wagner shares several head-turning examples.
Case Study: PW Communication
For developers, extending ObjectPAL with DLL's may be the most
important PW capability. The icing on the DLL cake is that it also
happens to be easy. Here's an example that enables PW to go on-line
with a remote host.
ODAPI Configuration
ODAPI is the centerpiece of PW and Quattro Pro for Windows interoper-
ability. Configured properly, it allows these products to function
seamlessly. Ms Loud gives us this part of the interop puzzle.
Taming Net File Chaos
With the plethora of product versions and data sharing schemes, the
interoperability landscape can sometimes look pretty bleak. With
this comprehensive guide however, Mr Kadanavich lightens the outlook.
Paradox Pro
Interoperability is nothing new to users of Paradox and Quattro Pro.
Mr Kadanavich has all the information you need to get things working.
Paradox for DOS/Windows Interop
These are interesting times for Paradox users. Many of us need to
use Paradox 4.0 and Paradox for Windows on the same data. This is
perfectly possible, but there are some tricky aspects as Mr Kellen
points out.
Paradox Surgeon
PW introduced some great new field types for Windows use. But
Paradox 4.0 throws up its hands and declares them "unknown". Don't
fret. Via ingenious use of DataEntry mode, Dr Faulkner presents a
new and improved Tools | Info | Structure.
PAL Toolbox
The Paradox 4.0 event model can present quite a challenge. Wouldn't
it be great if there was a ready made kit of generic event handling
routines? Thanks to Mr Paolini and this month's Toolbox, there is.
PAL Tech
This month Mr Todd completes a two-part Editor suite. This time we
learn how to parse input from Dialog information service.
Paradox Tricks & Tips
Forced to work with directory trees from hell? PW aliases are the
blessing you're looking for. Let Dr Jensen explain the ins and outs.
OPAL 101
Date/time data is some of the more important. So it's great that PW
has a DateTime object type with plenty of associated methods. But
there's no DateTime field type for table storage! Mr Sarrenburg
explains why this is no problem.
Objectively Speaking
There are three important properties common to every UIObject:
First, Next, and Prev. Unfortunately, the PW documentation treats
them like a secret. Mr Morwood has decided to spotlight these tools.
PAL100
Ready to make the leap to PAL? Mr Brown begins a series designed to
get you up and running with the Paradox Application Language. This
month's article pits a query against a SCAN. See who wins.
PW Multimedia
To round out our interoperability extravaganza, we're finishing the
issue with a survey of multimedia products. Whether you'd like to
tap into sound, photographs, or full-motion video, it's here.

Corporate Paradox
If you work at a large company, chances are most of the company's
data is in a SQL database. And your Paradox data is on the LAN.
Client/server is the answer and Paradox happens to be great at it.
Client/Server and the Paradox SQL Link
Borland's long-standing offering as the "client" in a client/server
system is Paradox SQL Link. This month Mr Tandowski provides an
introduction to this important tool and the capabilities of PAL with
embedded SQL.
PW SQL Access Now
The Paradox for Windows version of Paradox SQL Link isn't available
yet. Does this mean we can't get to SQL data from PW? Mr Wright
says no! All it takes is some ObjectPAL and a DLL from Q+E.
The InterBase Connection
Borland has big plans for InterBase, its very own SQL server. Its
loaded with features including a unique multi-generational architec-
ture. Mr Sharp gives us the lowdown on an emerging product.
A Matter of Protocol
It appears in articles. It comes up in conversations. But just what
is TCP/IP? It's just the machine-to-machine link that makes clint-
server possible. Our Network Editor, Gary Praegitizer, demystifies
this important network communications protocol.
Up and Running: NetWare SQL
Novell offers a SQL server that is native to the world's most popular
network operating system - their own. Mr Grove provides us with an
introduction and setup instructions for using it with Paradox.
Up and Running: Oracle Server
Oracle has the largest installed base in the SQL server arena, so its
not unlikely that you'll run into it. Mr Grove puts the product in
focus for Paradox users and tells us what it takes to get connected.
Up and Running: InterBase
From TCP/IP to PING to FTP to AWK, there are enough UNIX acronyms to
make any poor DOS programmer's head spin. Fear not. Mr McIntosh and
Mr Robinson blaze a trail into UNIX we all can follow.
A SQL Primer
Your comfortable with Paradox QBE, but SQL is just a meaningless
acronym. If you know QBE, you already know the hardest part of SQL-
the principles of querying a database. The rest is just syntax.
Murphy's Dream
For all the advantages that client/server architecture offers, it's
no cake walk. In fact, with poor planning, your client/server imple-
mentation could become a bona fide disaster. Mr Slater helps us go
in with our eyes wide open.
Paradox Tricks & Tips
One early estimate of PAL/ObjectPAL compatibility was "less than zero
percent". Apparently, that was a little pessimistic as Dr Jensen
proves this month by converting PAL queries into ObjectPAL.
For the Record: Part IV
You've seen the graphics. You've heard the music. Now it's time for
a little ObjectPAL. This month Mr Koulouris takes his PW multimedia
extravaganza one step further by adding the programmatic side of PW.
Paradox Surgeon
Undocumented commands never seem to lose their allure. This is
especially true when the commands can alter the basic configuration
of Paradox. This month, the Surgeon opens up the patient and reveals
the secrets of CONFIGURE.
The Competive Edge
Are you beginning to believe that all the Paradox excitement is
occuring on the Windows side of things? Au contriare! Mr Goodman
has always had a visual knack. This month its animated icons.
SQL Servers
Paradox SQL Link supports several SQL servers on a variety of platforms
with a variety of features. Sorting them all out can be perplexing.
To help us out, Mr Koulouris offers a survey of SQL RDBM's.
