How do I make EXE files with Turbo Pascal?
In Turbo Pascal, in the compile menu, make sure that the COMPILE TO
option is set to COMPILE TO DISK. When you compile, make or build
your program then you will create the file XXX.EXE, where XXX is the
name of your .PAS file.
----------------------------------------------------------------------
Will Delphi V2/3/4/5/6/7/.net/D2005 do DOS programs as well as
Windows?
Delphi V2 and later are for Windows 9x and Windows NT/XP. They are
not DOS products. They can create 32-bit console mode apps, but
they will not create DOS apps.
If you want DOS apps from a Delphi Product then Delphi V1 can do
them with some work on the RTL. See
http://mx1.org.uk/usenet/
DCC32 -cc program.pas
is worth trying on some BP/TP programs mainly computational in
nature.
There is also wdosx, a winapi emulating dos-extender. Afaik this
also works for 32-bits Delphi's. [MvdV]
----------------------------------------------------------------------
Is there a Borland Pascal Mailing list?
No, there is not.
There is a mailing list for Virtual Pascal (see below) on Yahoo.
Read access is here:
http://tech.groups.yahoo.com/group/vpascal/
The old Topica list is still readable at
http://www.topica.com/lists/virtualpascal/read
----------------------------------------------------------------------
Is it possible to 'decompile' Pascal EXEs or TPUs?
No. Too much information is lost in the compiling process. For a
more detailed explanation see Prof. Timo Salmi's FAQ.
It is possible to get a *reasonable* disassembly to assembly
language only
- try
http://www.hex-rays.com/idapro/
The FLIRT technology that comes with IDA will identify most routines
of the _original_ Borland RTLs. It will 'miss' interrupt routines,
but due to its interactive nature, these can be added very easily.
----------------------------------------------------------------------
What were the Borland Pascal Products?
In essence, Borland Pascal was the 'professional' product, whilst
the Turbo Pascals were 'hobbyist' products.
Discontinued versions
Turbo Pascal 7 (Dos)
Turbo Pascal for Windows 1.5 (Win)
Borland Pascal 7 (DOS, WIN 3.1, Pmode)
Borland Pascal could do everything that both Turbo Pascals could
do, plus:
. Compile for 16 bit DOS Protected mode (less memory constraints)
. Full Run Time Library Source code
. Lots of assorted debugging and programming tools
There was an update to TP and BP to v7.01, but this is no longer
available. V7.01 still has VER70 defined. If you really want to
pay big bucks for an old version, you might try here
http://www.emsps.com/oldtools/borland.htm
for the possibilities of obtaining a used copy of the various
versions of the Pascal compilers produced by Borland. You may also
find copies of BP7 for sale on Ebay at
http://www.ebay.com/
Needlessly to say, there are also other options...
----------------------------------------------------------------------
Are there any freeware Pascal compilers?
- FPC Pascal
# Free Pascal, now (2011-05-22) at version 2.4.4, is a compiler for
32-bit and 64-bit CPU architectures such as Intel x86, Amd64/x86_64,
PowerPC, PowerPC64, Sparc, ARM. The discontinued 1.0 version also
supports the Motorola 680x0. The following operating systems are
supported: Linux, FreeBSD, Haiku, Mac OS X/Darwin, DOS, Win32, Win64,
WinCE, OS/2, Netware (libc and classic) and MorphOS.
It comes with a cross-platform Run-Time Library, many interfaces to
existing libraries, and a large set of non-visual classes in the
Free Component Library. Last but not least, a text-mode IDE exists
on various platforms, and FPC comes with 1800 pages of documentation.
The compiler is licensed under the GNU General Public License. The
Run-Time code is licensed under a modified version of the Library
General Public License, which allows to use it in a commercial
application.
Comes with full Pascal source and compiles itself.
http://www.freepascal.org/
- GNU Pascal
GNU Pascal is a portable 32/64 bit compiler system. It supports the
language of Borland Pascal V7 as well as ISO Standard Pascal, a
large subset of ISO Extended Pascal and other extensions (see
http://www.gnu-pascal.de/gpc/h-index.html
GNU Pascal is part of the GNU family of compilers, runs on all
platforms supported by GNU C, including DOS, OS/2 and MS-Windows
9x/NT, Linux, *BSD and other Unix-compatible systems and can cross-
compile between these platforms.
Full C source and precompiled binaries for several platforms are
available from:
http://www.gnu-pascal.de/alpha/ (Sources)
http://www.gnu-pascal.de/binary/ (Binaries)
There is a GNU Pascal mailing list,
gpc@gnu.de. To subscribe, write
an email with the body "subscribe gpc
your@email.address" to the

Framework Pascal (Formerly TMT Pascal)
Framework Pascal, now at Version 6.1, is a 32-bit compiler with Turbo
Pascal syntax and is quite compatible with Turbo Pascal.
Framework Pascal is available from
http://www.frameworkpascal.com/products.htm
- Virtual Pascal
Virtual Pascal, now at Release V2.1 is free. It fully supports DOS
and Delphi plus Turbo Vision has been ported to 32 bits. There is
incomplete support for (x86 architecture only) Linux.
http://vpascal.ning.com/
On 22 August 2003 Allan Mertner made the modified-for-VP sources
of TurboPower's Object Professional libraries available on the VP
site. Legal uncertainties have led to their removal.
On 24 August 2003 Allan Mertner announced that he is looking into
Open Sourcing the compiler. More info and discussion about this
can be found on the Virtual Pascal mailing list, which is archived
on Topica,
http://lists.topica.com/lists/virtualpascal/read
A direct link to the post that kicked off the discussion is
http://lists.topica.com/lists/virtualpascal/read?sort=d&start=2665
On 3 April 2005, Allan Mertner announced the death of Virtual
Pascal. He will continue to run vpascal.com for "a few more years",
but development will cease - the main reason for doing so is the
fact that the compiler is written in assembler and it cannot
realistically be changed to add new features. Due to copyright
restrictions, the source will not be made available. There is a
small possibility that Allan might produce one more maintenance
release.
See Also Section 4 on Borland's release of TP compilers.

----------------------------------------------------------------------
How to use run-time checks?
The Borland compilers can be set up to trap a substantial number of
Run-time errors. In the early stages of program development it is
advisable to enable _ALL_ error-checking options, i.e.
- $I+ to detect I/O errors
- $Q+ to detect overflows (BP/TP7 only)
- $R+ to generate range-checking code
- $S+ to detect stack overflows
- $T+ to enable type-checked pointers
- $V+ to enable strict checking of Var-strings
The $T+ option is a _compile-time_ error-check. It does not carry
any run-time overheads!
Using all of them will in many cases enable you to find problems
without having to resort to the newsgroup.
Once a program runs correctly, even with input no sensible user
would ever enter, you might want to disable all error-checking, with
the possible exception of I/O checking. However, the high clock
frequencies of todays CPUs might make the resulting reduction in
execution time minimal. As an alternative, it might be advantageous
to put fully debugged, well tested and frequently executed code into
a separate unit that is compiled without any error-checking.
----------------------------------------------------------------------
How to use Random/Randomize?
The Randomize procedure is used to initialize the seed of the random
number generator (RNG) with a value derived from the system time. It
should only be called once, at the very start of a program. Calling
it more frequently, especially in loops on fast CPUs, may result in
it being re-seeded with the same seed on many iterations, which in
turn results in the Random() function producing the same 'random'
number over and over again!

4 Compiler and unit downloads **********************************************************************
4.1 Borland compilers for download **********************************************************************
Borland has placed three older versions - V1.0, V3.02 and V5.5 of
the Turbo Pascal compilers on the Internet for download at
http://edn.embarcadero.com/museum/antiquesoftware
As regards any licensing issues, Borland have stated
"Since the software is old, you can do whatever you want with it.
You can freely distribute the executable version of programs
that you develop."
Brief highlights of the compilers [V3.02 is bug fixed version of
V3.0 and V7.01 is bug fixed version of V7.0]
TP V1.0: produces .com files, 64K maximum for code, data and stack
but you can use the heap for variables.
TP V3.0: produces .com files, 64K each for code, data and stack.
Heap can be used. Implements overlays but careful planning needed to
avoid thrashing the disk. [Hint: Use a RAMdisk]
# Information about the internals of TP 3.01a and a program to generate
# a commented disassembly of that specific version (i.e. *not* the
# version at the Embarcadero site!) can be found at Pascal Dornier's
# site,
#
#
http://www.pcengines.ch/tp3.htm
TP V5.5: produces .exe files, 64K each for code, any unit, data and
stack. Heap can be used. Implements decent overlay manager. First TP
that can use OOP [Object Orientated Programming]. Users of this
version who need the Delay procedure should read the notes about
RTE200 in Section 3.
TP V7.0: OOP plus Turbo Vision and inline assembly language
available. Users of this version should read the notes about RTE200
in Section 3.
# Igor Funa has written a TP7 compatible compiler. It comes in two
# versions, a 16-bit one that can be compiled with TP7, and a 32-bit
# version that can be compiled with Delphi 7. Both compilers generate
# only 16-bit code. Some source is avalaible on the site, but the full
# source will set you back USD 149.95. It can be found at

**********************************************************************
4.2 Replacement units for download **********************************************************************
Borland made the source of the Run-Time Library (RTL) of its later
products available to the end user, either for an additional fee or,
in the case of BP7, as a "bonus" disk.
Using the source it was theoretically possible to write improved
units.
**********************************************************************
4.2.1 Replacement SYSTEM units for download **********************************************************************
At the moment there are FIVE of them available on Garbo. They are:
- for TP 5.5:
ftp://garbo.uwasa.fi/pc/turbopa45/syst55c.zip by James LeMay
- for TP6:
ftp://garbo.uwasa.fi/pc/turbopa6/sys60a.zip by James LeMay
ftp://garbo.uwasa.fi/pc/turbopa6/tpl60n19.zip by Norbert Juffa
- for TP/BP7:
ftp://garbo.uwasa.fi/pc/turbopa7/bpl70n16.zip by Norbert Juffa
ftp://garbo.uwasa.fi/pc/turbopa7/bpl70v20.zip by Robert AH Prins
The units by James LeMay are just faster, Norbert Juffa's units also
have an increased smart-link granularity because he split up most of
the original sources into several parts. However, most notable about
the Norbert Juffa libraries is the greatly improved 6-byte real
arithmetic, which is now as IEEE-754 compliant as possible within
the restrictions of the format. Needlessly to say, Norbert's SYSTEM
units are also substantially faster than Borlands original versions.
The unit by Robert Prins is based upon Norbert Juffa's code, but it
has been enhanced significantly. A few of the major changes are:
- it is based on the BP 7.01 RTL
- it requires a 32-bit CPU and a 387 class FPU if FPU datatypes are
used
- the code has been made Pentium+ friendlier by replacing most of
the slower CICS type instructions by their RISC type equivalents
- the code is even more smart-link friendly
- both the real (TURBO.TPL) and DPMI (TPP.TPL) libraries include a
non-RTE200 smartlink-friendly CRT unit
- both contain a much more smartlink-friendly DOS unit (all original
get/set routines have been broken in two)
- the FPU based Trunc, Int and Round functions were made re-entrant
There is an additional very small "SYSTEM" unit available for BP7,
but it is stripped down to such an extent that, to quote the author
"... you can't use all the features that the standard RTL has."
The name of the archive is BPC-TRTL.ZIP and using Google you should
have no trouble finding a copy.
Here's an incomplete list of removed features:
- All System unit procedures, such as WriteLn
- All runtime error checks (you have to use {$R-,S-,Q-,I-} mode)
- Return codes (ignore the runtime error messages that IDE shows)
- Floating-point data types (you have to use {$N-,E-} mode)
- Heap manager (allocate memory using DOS calls)
- String handling routines (including the + operation)
+ Some of the LongInt operations: *, /, shr, shl (they still work
with Integer)
+ Large variable assignments (that involved a procedure call)
Also, note that you can't compile programs with debug information
for standalone debugging. However, you can use the integrated
debugger, or you can compile your program with the standard RTL for
debugging (and use TinyRTL after the bugs are fixed). Don't forget
to save your program before you compile it! The compiler crashes
with an internal error if you occasionally use some of the removed
features.
**********************************************************************
4.2.2 Replacement CRT units for download **********************************************************************
Following work on a replacement CRT unit to primarily fix the RTE200
bug in T/BP7, two replacement CRT units are now completed. CRT units
are included for TP V5, 5.5, 6.0 and 7.0x including protected mode
units for BP7.0x. Pedt Scragg's ZIP file also includes precompiled
units for Delphi 1. Robert Prins' unit contains all .OBJ files so
that users of D1 can roll their own. This unit is included in
BPL70V20.ZIP.
The replacement CRT units also include code to allow use of extended
keys such as F11 and F12 with ReadKey and, if using other than 40x25
text mode or 80x25,43,50 text mode should not reset text screen to
80x25.
Be aware that the unit by Robert Prins (rpcrt100.zip) contains 386
instructions. It will not run on 8086/88/286 systems, but does not
test for such systems!
Pedt Scragg's unit:

**********************************************************************
4.2.3 Replacement OVERLAY unit for download **********************************************************************
Available on Garbo is a replacement Overlay unit. The unit comes
with the never-made-available by Borland reconstructed sources of
the original unit. The file containing the replacement unit also
contains an improved version of Wilbert van Leijen's OVERXMS.ASM
source, but not the other files in WvL's original archive!
Both units contain 386 instructions and both are included in
BPL70V20.ZIP.
Download from:
ftp://garbo.uwasa.fi/pc/turbopa7/over-120.zip
ftp://garbo.uwasa.fi/pc/turbopas/overxms.zip (WvL's original unit)
**********************************************************************
4.2.4 Emulator sources for download **********************************************************************
Borland never made the sources of the hard- and software emulator
files available. Reconstructed sources, including those of the
improved version of the hardware emulator by Norbert Juffa, with
instructions on how to add them to the RTL are also available on
Garbo:
ftp://garbo.uwasa.fi/pc/turbspec/em8x-110.zip
Newer, further optimized and far better commented, versions can be
found in BPL70V20.ZIP.
**********************************************************************
5 Using Borland compilers on modern Operating Systems **********************************************************************
It is possible to use TP/BP and the programs they compile on 64-bit
versions of Windows and both 32- and 64-bit versions of Linux, but
it might be more advantageous to use either Delphi (for Windows) or
FreePascal (for Windows and Linux) to do so.
**********************************************************************
5.1 Windows 64-bit **********************************************************************
64-bit versions of Windows XP/Vista/7 no longer support running the
16-bit programs generated by the various versions of Borland and
Turbo Pascal. It may be possible to run BP/TP non-Windows programs
using DOXBox
http://www.dosbox.com/ currently at version 0.73, with
version 0.74 apparently just around the corner.
Another option, for users of W7 Ultimate is to download the XP
emulator.
**********************************************************************
5.2 Linux **********************************************************************
To run TP/BP and the programs they create on Linux you can use
DOSEMU
http://dosemu.sourceforge.net/
**********************************************************************
5.3 Virtual Machines **********************************************************************
A final option, usable for both 64-bit Windows and all versions of
Linux, it to download a virtualisation program, such as
- Oracle's VirtualBox
http://www.virtualbox.org/
- Bochs
http://bochs.sourceforge.net/
and run DOS or Windows in a virtual machine.
