3. What's the difference between Borland Pascal with Objects
7.0 and Turbo Pascal 7.0?
Borland Pascal with Objects 7.0 includes features aimed at
professional DOS and Windows programmers including the
ability to create DOS Protected Mode (DPMI) applications,
DOS Dynamic Link Libraries (DLLs), as well as a more
complete set of professional tools including Turbo
Debugger, Turbo Profiler, Turbo Assembler.
Turbo Pascal 7.0 is a subset of Borland Pascal with Objects
and includes the ability to create DOS real mode programs.
It includes the high capacity IDE, ObjectBrowser and
extended Turbo Vision application framework, but does not
support DOS Protected Mode (DPMI) or Windows development.
4. Who uses Pascal?
Borland has shipped over 2,000,000 units of Pascal. The
largest segment of Pascal customers is professional
programmers, who make up 40% of the market. Pascal is
widely used for internal corporate application development,
by consultants and VARs in vertical markets such as
health-care and construction and by commercial "shrink
wrap" software developers. Borland Pascal with Objects 7.0
is targeted directly to professional programmers who want
high productivity development for DOS and Windows.
Pascal is also the most popular language for learning
structured and object-oriented programming. Turbo Pascal
7.0 is targeted at new programmers who want the fastest way
to learn object-oriented programming.
5. Are there commercial applications written in Pascal?
There are many commercial "shrink wrap" software products
written in Pascal. These products include leading CAD
packages such as Autodesk's Generic Cadd, Fast CAD, Turbo
CAD, Claris' Filemaker Pro for Windows, leading tax
preparation software such as Tax Cut, Turbo Tax, Parson's
Personal Tax Edge, financial packages such as Money
Counts, communications packages such as QModem, Tapcis,
Ozcis and many others.
6. Does Borland use Pascal to develop any of its products?
Borland has a major commercial application under
development using the new Borland Pascal with Objects 7.0.
Borland has not yet announced the name of the application
being developed in Pascal.
In addition, the DOS IDE for Borland Pascal with Objects
7.0 is written entirely in Pascal using the Turbo Vision
application framework.
7. Why has the product name changed?
We've called the new professional Pascal programming system
"Borland Pascal with Objects" to reflect the professional
positioning of the product and provide greater consistency
with the C++ product line. Borland continues to offer Turbo
Pascal 7.0 and Turbo Pascal for Windows 1.5 for entry level
programmers who do not need all of the advanced
capabilities that professionals require.
8. What are the benefits of creating DPMI applications?
By using Borland Pascal with Objects 7.0 you can create DOS
Protected Mode (DPMI) applications that break through the
640K barrier and access up to 16 megabytes of memory for
code and data. This gives you higher capacity for dealing
with larger amounts of data for more efficient processing.
9. How do you create DPMI applications?
You can simply select the Compile Target menu choice to DOS
protected mode and recompile existing programs. The
compiler will create an EXE with a real-mode stub that
automatically loads the DPMI server and runtime manager and
then switches to protected mode and runs your program.
10.What DPMI technology do you use? Is there a royalty
charge?
The DOS extender is fully compatible with the DPMI
specification and is based entirely on Borland technology
and was used in the latest version of Borland's Paradox 4.0
database. No royalty payments or runtime charges are
required to distribute protected-mode applications written
with Borland Pascal with Objects 7.0.
11.What is the benefit of DOS DLLs? How do you use them?
By creating programs as Dynamic Link Libraries (DLLs) you
are able to share the same source code and binary file
between both DOS and Windows programs. For example, a
typical business application might be constructed with a
DOS Turbo Vision user interface and a Dynamic Link Library
that does "back end" computation and data processing. The
back end DLL can be shared with a Windows version of the
program that uses an ObjectWindows user interface. The
source code to the DLL does not require any changes to work
in Windows and, in fact, does not even need to be
recompiled to work in Windows.
In the same way, you can compile C or C++ code as a Dynamic
Link Library using Borland C++ or any other compiler and
link that code into Windows or DOS applications written
with Borland Pascal with Objects. No other language offers
the ability to create and link to
DOS and Windows DLLs.
12.What are the new optimizations in Borland Pascal with
Objects 7.0?
Several new compiler optimizations have been added so that
existing programs can be recompiled for faster performance.
These include 32 bit LongInt math operations, redundant
pointer load suppression, optimized sets, constant
parameters and faster string and file I/O routines.
13.Does Borland Pascal with Objects 7.0 include visual
resource editing?
Yes, Borland Pascal with Objects 7.0 includes Borland's
Resource Workshop, a fast, powerful way to visually created
user interface elements including menus, dialogs, bitmaps,
cursors, icons and so on. There are also third party visual
resource editing tools available for use with Turbo Vision,
including Blaise's Turbo Vision Development Toolkit.
14.Do developers need to buy the Microsoft Windows Software
Development Kit (SDK) to use Borland Pascal with Objects
7.0?
No, Borland Pascal with Objects includes everything you
need to develop DOS and Windows applications. It is fully
compatible with Windows 3.0 and 3.1. It includes:
o Windows Integrated Development Environment
o Borland Pascal with Objects command line compiler
o Windows 3.1 interface files
o ObjectWindows application framework
o Resource Workshop
o WinSight
o WinSpector
o Resource Compiler
o Help Compiler
o Turbo Help hypertext system
o Sample programs
o Complete Windows tutorials
15.Does Borland Pascal with Objects 7.0 include help on new
Windows 3.1 API functions?
The on-line Turbo Help system has been completely expanded
to provide more detailed descriptions of Windows API
functions as well as new entries for all new Windows 3.1
features. There are over 4 megabytes of on-line help. In
addition, we are making available a complete printed
reference 3 volume set of all Windows API calls for $39.95.
This three volume set includes Pascal definitions of all
API calls and data structures.
16.Is the Runtime Library Source Code included?
As a special bonus to purchasers of Borland Pascal with
Objects 7.0, we will include in all upgrades a retail
purchases the Application Frameworks and Runtime Library
Source Code. This includes the complete source code to the
Turbo Vision and ObjectWindows application frameworks and
is a $195 value.
17.Is there a CASE tool for Pascal? What is Protogen?
Since there are many professional programmers who are new
to Windows development, Borland will be making available a
version of the Protogen CASE tool that generates Pascal
source code. Protogen allows developers to draw their user
interface in Windows and then automatically generate much
of the standard Windows code that is required. This makes
it much easier to get started in Windows and
object-oriented programming. Protogen will be made
available for the special price of $49.95 to purchasers of
Borland Pascal with Objects 7.0.
18.Does Borland Pascal with Objects work with the new Paradox
Engine?
Yes Borland Pascal with Objects works with the latest
version of the Paradox Engine 3.0. Paradox Engine 3.0
includes support for real mode, DOS protected mode (DPMI)
and Windows application development in Pascal. It also
includes a complete object-oriented database framework for
Pascal programmers as well as faster and more memory
efficient performance. Paradox Engine 3.0 is available
separately.
19.What is the minimum hardware configurations for Borland
Pascal with Objects 7.0 and Turbo Pascal 7.0?
Borland Pascal with Objects 7.0 requires an 80286 or higher
processor, 2 megabytes of memory, a hard disk. For Windows
development you must also have Windows 3.0 or later,
graphics (EGA, Hercules, VGA or higher resolution) and a
mouse.
Turbo Pascal 7.0 requires 720K of disk space and 512K of
memory. A hard disk and 80286 or higher processor is
required to use the high-capacity IDE.
20.How do the new products affect the existing product line?
Borland Pascal with Objects 7.0 and Turbo Pascal 7.0
replace the existing Turbo Pascal Professional 6.0 and
Turbo Pascal 6.0 products. Turbo Pascal for Windows 1.5
remains on the market as an entry level object-oriented
programming system for Windows.
