Can anyone suggest a way to allocate a 64KB memory, in an IBM PC AT or a
clone, which is ALIGNED to the 64K boundary (0x____0000)?

From: David Camp <C04661DC@WUVMD>
I read your inquiry about allocating an aligned 64K block. I did
this in a previous program. Here is a code fragment that worked for me.
Notice that I had to allocate twice as much as needed in order to insure
that two boundaries were in the field.
unsigned int far * data_buffer;
unsigned long int_buffer;
union
{
unsigned long long0;
struct
{
unsigned int short1;
unsigned int short2;
} s;
} int_holder;
{
/* Allocate the data buffer. */
data_buffer = (int *) halloc(65536,2);
int_holder.long0 = (unsigned long) data_buffer;
int_buffer = (((long) int_holder.s.short2)*16) + int_holder.s.short1;
int_buffer = int_buffer - (int_buffer % 65536) + 65536;
int_holder.s.short2 = (unsigned int) (int_buffer / 16);
int_holder.s.short1 = (unsigned int) (int_buffer % 16);
data_buffer = (int far *) int_holder.long0;
}

Subject: Windows .TIF File Format
A few weeks back I posted a query on the net about getting digitized
images into the Microsoft Windows envrionment. Since that time, I've had
several (4 or more) conversations with Microsoft technical personnel.
Each, unfortunately, has had a different story about file formats for
Windows.
One tech rep said that, as long as my files were saved out in .TIF format
I could get them into Windows without any problem. Stupid me, I forgot to
ask how. So I called back again, and the next tech rep did not know about
.TIF at all. He did call me back and tell me that I can move my images to
Aldus Pagemaker and from there into the Windows clipboard. I suspected
that the Windows Development Kit might have other information, but today's
call quashed that hope. No utility program to transfer .TIF files, but a
description of the file formats if I wanted to write my own program.
The funny thing is that the .TIF format (tagged image format) was
supposedly developed jointly by Microsoft and Aldus. If that's so, how
come Microsoft seems to know so little about it. Yet... all of the
graphics programs I've looked at --my salvation seems to be in programs
for desktop publishing-- support .TIF.
I'm working on a hypertext project in Guide. I want to put scanned images
in with my text. I also want to do them in color. I can do this easy as
pie on a Macintosh and still have a "programable" language to flesh my
project out with (hypertalk). I sure as heck ain't going to write a
program to translate .TIF into MS-Windows. I suppose that for the
present, the bottom line with this is tuf.TIF.
I have several promising programs on the way and an offer from a guy who
makes a device that scans slides into almost any format that he WILL get
the slide that I sent him into Windows. I will be happy to continue this
saga later, programs in hand. Maybe it will save someone else some time
and frustration. Thanks to those who responded to my original plea for
help. Now, where's the number of my Apple sales rep?

Subject: MSC 4.0 interrupt (^C) handler help needed
-From: Creps <creps@silver.bacs.indiana.EDU>
- I'm trying to get an interrupt handler to work in MSC 4.0 that will
-handle ^C's at any time...
-for(i=1;i<100000;i++) if (i % 10000 == 0) fprintf("%d",i);
-int interrupt()
-{
- fprintf("*** int ***");
- signal(SIGINT,interrupt);
- return;
-}
1) I assume that you meant either fprintf(stdout,"%d... or printf("%d...
2) What is missing is fflush(stdout); after your fprintf in the interrupt
routine. Fprintf only buffers stuff for output until the buffer is full
or a newline is found, or whatever, at which time it effects the fflush.
You are adding "*** int ***" to the buffer, but not flushing it to the
display device.

Subject: Turbo C vs Quick C
>From: Ric Messier <ram@lscvax.uucp>
The February issue of PC TECH magazine has a C compiler survey and a good
article comparing the merits and performance between Turbo C and Quick C.
The author suggests that Turbo C edges Quick C in most categories: Quick C
provides some minimal symbolic debugging while Turbo C does not; Turbo C
supports several memory models while Quick C only supports large.

^^^^
An alternative solution is to simply be careful and not break the rules.
DOS has always been very unforgiving in this area (it's as much a victim
of the Intel architecture as we are), and blaming any compiler because it
"lets" us screw up is a bit tacky.

(a) You are right, this is VERY simple. However, this also only provides
a binomial distribution between 0 and 12 (or however many numbers you use)
while you are aiming for a gaussian distribution which is unbounded.
A much better (from the point of accuracy, not from the point of ease of
implimentation) transform is to use Box-Muller. Given two random
variables X1 and X2 which are both U(0,1), calculate
Y1 = sqrt (-2*ln X1)*cos 2*pi*X2 and Y2 = sqrt (-2*ln X1)*sin 2*pi*X2
Y1 and Y2 are both N(0,1) !!!

Try Final Word from Mark of the Unicorn here in Cambridge. It includes a
editor which is a lot like Emacs and a formatter which is a lot like
Scribe. Depending on how fancy your Scribe macros are, you may or may not
have to fiddle your document to get FW to eat it.

Yes, that is correct but while the BBS manager can not be held accountable
and forced to pay damages, an injunction order can be placed on him to
force him, and any others who are distributing your program, to cease
distribution. I believe (although I'm not 100% sure) that after you become
aware that you are distributing copyrighted software, if you don't stop
giving it out, you are liable for damages.
The basic problem with the copyright issue as applied to software is that
not only is it a gray area as far as laws are concerned, but more oft than
not the judges and lawyers do not really understand the mechanisms
involved. (how the data is stored, what constitutes a copyrightable or
patentable algorithm, etc..). It is best not to expect a consistent or
100% sane behavior from the courts until a lot more cases have been tried
and some sort of pattern can be discerned. Until then I will be expecting
lots of surprising developments and judgments.

Subject: Errors with 3270 Emulation on Token-Ring
We recently set up a Token-Ring with 13 user PS/2 Model 50s and a Model 60
file server and 3270 gateway. Everything works fine when the net first
starts. But after a while, after people actually start using files on the
server and getting in and out of 3270 emulation, we start getting strange
errors. People can't log in and people who are already logged in start
getting NET810 and NET801 errors.
Sounds like the server crashed, right. Here's the strange part: From the
keyboard of the server nothing looks wrong! NET still brings up the
menus. NET SHARE still lists the people the server thinks are logged in.
NET ERROR doesn't list any errors. We can Alt-ESCape to the gateway and
display the status panel, even shut it down and restart it. Sometimes a
people will still be able to get at files on the server or continue a 3270
session while others just get errors.
I've rechecked the startup parameters twice, especially /SES and /CMD, and
they look good. Besides which, we start getting errors with only 6 or 7
people on.
We're using the new device drivers, not TOKREUI and NETBEUI; IBM PC LAN
V1.20; IBM 3270 Emulation 3.03; and no TSRs. Has anyone else seen
anything like this? Any suggestions on how to dig more status information
out of the server?
