It is not uncommon for bugs to hide when the debugger is loaded. It
often means that the bug is not a simple coding error, but rather a
poke to an invalid memory location, possibly overwriting part of the
program.
One approach is to load the program into the debugger, and then run it
full-tilt. If the bug occurs, the debugger might let you observe the
state of the program after the error. Of course, this approach is
hit-or-miss.
The brute-force and most expensive solution is to buy a hardware
debugger. This is a bus board that has an interface to an external
monitor, sometimes another PC. The debugger is run on the external
device, and the program runs as if the debugger is not present. The
hardware device can perform breakpoints without altering the
configuration of the software in the PC.
The time-honored and most difficult, but often very rewarding, approach
is to make printouts of your code, go to the library, and just read.
Many bugs can be found this way, but one tends to get burned out,
needing a long break after the process. This is often more effective
if you simply explain the code to a friend. You will often find the
bugs yourself as you find it impossible to explain the errant section.
Also consider using the old 'debug' commands that comes with Dos. It
can only be used effectively by people who understand assembly
language, but it is less intrusive of the environment and is very small
compared to CodeView.
Perhaps the most persistent bug I ever found was diagnosed by simply
thinking about the program's behavior, and guessing what section was
the most likely to be in error. I then inspected the printout of that
section, and found some code that was logically correct, but confused
the compiler when an array crossed a 64K segment boundary. I recoded a
memory access as an array reference instead of as pointer arithmetic,
and the program stopped failing. Your mileage may vary.

Subject: Connecting two PC's
Robin van der Kuil recently asked about connecting two PC's together
through serial ports. Recently I installed The $25 Network on two PC's
using an 80 foot cable w/null modem. Disk drives and printers on one
machine are available from the other machine. The hard disk of the
remote machine can be accessed as though it is attached to the machine
you are using with only a slight delay evident. Programs on the hard
disk of the remote machine can be executed on your machine.
The program is not in the public domain nor is it shareware, but at
$25.00 the price is hard to beat. The company will also supply a
custom length cable with null modem at a reasonable price. The address
is: Information Modes, P.O. Drawer F, Denton, Texas 76202, phone (817)
387-3339.
I am a happy customer and wish I had discovered the program sooner, but
I have no other connection to the company (i.e., usual disclaimers).

Subject: Data Base Package Recommendation
In INFO-IBMPC Victor Bagley asks for recommendations about database packages.
Asking for database packages recommendations is kind of like asking for
Word Processor recommendations, or about religion or politics. Your
bound to get lots of opinions. For what its worth, here's mine.
dBASEIII+ Outmoded. Will handle small applications if you already have it
but don't buy it.
dBASEIV Don't even take a free copy of version 1.0. Version 1.1 seems to
have all the bugs worked out. AT's release of multi-platform
versions make it worthy of consideration if you are in that kind of
environment.
FOXPRO My choice if you need user interface to the interpreter. Fast.
Fairly good application development. Version 2.0 to be released
shortly (?) promises even greater things.
PARADOX The choice if you are going to integrate spreadsheet (QUATRO PRO)
and database applications. Files are not .DBF.
CLIPPER Version 5.0 is buggy. Fix is promised soon (?). Summer87 version
still doing the job. The choice for straight application
development. The only one that produces .EXE files. This is a
compiler not an interpreter so there is NO dot prompt direct user
interface. Great variety of third-party tools to do almost
anything you can imagine.
Feel free to call if I can give you any other information. Good Luck

I've used all the products)

Subject: Data Base Package Recommendations
You don't give much information about what you want to do, so it is
tough to give a recommendation, however here are some observations on
Paradox. Paradox is a truly easy to use, yet powerful database that
does not require you to be a programmer to get things done (unlike the
dBase/clone products). The query by example is easy to learn, but
gives you the power to really manage your data. Preparation of Forms
for viewing data and Reports for printing data is close to WSYSIG.
Reports have available up to 16 levels of grouping (for breaks/sorting)
and numerous ways to summarize data.
When programming is needed, Paradox makes it easy to work into it
slowly. The power of the programming language is extensive, however
and there's hardly anything you'll need that you can't do. In
addition, you can program in C or Pascal with the Paradox Database
Engine to use either of these languages for what they are good at, but
use Paradox for what it is best at.
In addition, Paradox is from Borland. It is a stable product, from a
stable company so you don't need to worry about the future of your
investment. Hope this helps.

First of all ... "less tolerant drives"? That is not true. [Sorry, if
this sounds like a flame (not intended).] Drives which format 720k
disk to 1.44mb are by-passing the HD sensor which are built in on the
drive. IBM PS/2 and some clones (ie. Headstart) do this. Normally,
drives are manufactured with this sensor placed in active. Teac is one
of the manufacturers which does this. On some systems, a Teac drive
may be told to format a HD disk to 720k by telling the CMOS that the
drive is a 720k drive (AST does this).
What I'd like to know is, does anyone know how to by-pass this HD
sensor on a Teac drive? That way I can format 720k disk to 1.44mb.
As for your question of what are the risks of formatting DD diskettes
to HD? I've been told that all disk media is made at the same time,
media which does not pass the HD test are then tested to pass DD. But
these disks are sampled from big batches. Therefore it is possible to
have good HD diskettes labelled as DD (720k) disks. My personal
feelings are to go ahead and format them HD. If they fail to work, go
and reformat them to DD. But since the prices for HD disks are
dropping, it may not be worth it.
I hope this helps. And I'd like to thank anyone who replies to my
question.
What I'd like to know is, does anyone know how to by-pass this HD

The 1.4MB disks have a higher "coercivity". This is a property of the
magnetic media. It allows data to be packed more densely, because it
requires a higher current to change a bit. The HD drives properly
apply the higher current at tighter intervals to achieve greater
density.
The DD disks have a lower coercivity. Some authors have vehemently
claimed that formatting them for high density will use a current too
large for the media. The close spacing of these bits with a potential
greater than the capacity of the media can cause them to interfere with
each other, causing data loss.
My only personal experience is that I have used some DD diskettes in HD
mode, and months later the data was irrecoverable. Other similar
diskettes were okay, but I have not done a thorough study.
The HD diskettes are not signifigantly more expensive than the DD ones,
so I think it is worth the money to protect your data. I personally
only format diskettes for their intended capacity. -David-

GNU gcc DOES run under msdos, though only for 386 or better machines.
I have two versions, both of which come with a dos extender. This
allows DOS programs to run in protected mode and use as much memory as
is available (something DOS has needed badly for a long while). Of
course this probably clashes with all sorts of memory resident
programs.
Yoshiaki Uchida's port of GNU gcc/gas/gld to MS-DOS was available
(around December) at ocf.berkeley.edu (128.32.184.25). No
documentation was available for the port I got (still in experimental
stages). I haven't been able to get back there to see if there's a
newer version.
Another port is from DJ Delorie, and is available from
grape.ecs.clarkson.edu (128.153.13.196), directory /pub/msdos/djgcc.
It has the Gnu C and C++, as, ld, ar, nm, strip, and also a 32 bit
runtime with virtual memory support. This port seems (to me) more
robust, and I've heard of newer versions.

Nope. Can't be done without a multitasking shell. I have no plans to

The price to upgrade your XT is as little as US$325 here in the States

Sorry 'bout that, but what a good excuse to treat yourself.

Perhaps it is being used for ROM or Video Shadowing. If you have these

The program AutoMenu from Magee Enterprises has a screen saver feature
that can be used two ways. One is a simple screen blank, the other

However, the message moves to only a few fixed locations on the screen.
After a while, THE SCREEN SAVER MESSAGE GETS BURNED IN! I have seen
this on both amber and white monochrome monitors.
I phoned Magee Enterprises about this and the person I talked to would

So, I am wondering if there are others out there who have experienced

would be much appreciated.
