assistant: NOTE: DCTEdit v0.04 [3]
That's exactly what it's doing, but the timer takes stuff out of the buffer
faster than the UART puts it in, so most of the time the buffer is empty and
it has to wait for it to be filled up again. But most of that's sorted out
now, there are other things going wrong which I'd rather think about myself a
bit more first.

Write your reply.

assistant: Hi Anthony,
You asked:
You need to cast the return from coreleft to unsigned long, as in small
model coreleft() returns an unsigned int, and also change the print
format specifier to match. So you need:
printf ("Free mem=%lu\n",(unsigned long)coreleft());
for a better overall display:
printf ("\nFree mem=%lu, Far=%lu, ",
                (unsigned long)coreleft(),farcoreleft());
If you cast as above that should be fixed. I also suspect your recall is
faulty and the random result was in the small model.
In my test code I added:
    else
      printf ("%p",x);
I got the same reply every time too...
I would expect the return value to be the same every time when called
under the same conditions in this simple instance.
I found xxxx:0004 everytime in large model, with xxxx the same for every
run under the same conditions but varied between IDE and standalone.
My results (BC 3.1, code modified as above)

Eek!
This'll be a lot more complex than a normal ascii sort since the
entries are split into more than one line.
Two possible ways I can think of are:
1.
First pass - Combine each entry into one line.
Second pass - sort.
2.
Load each entry into a structure or array and perform an internal
sort routine.
Number 2 will probably be easiest and definately fastest, but requires
you to have sufficient memory to handle this. Is that possible?
(I'll leave it to others to describe the sorting process, my methods
aren't particularly good...)

The rule didn't say anything about DOS. All it said (and still says but less
strongly worded) is that C programmers from all platforms should be able to
enjoy this echo. I would hate to see the echo becoming dedicated almost
exclusively to one operating system (be it Windows or something else). That's
why there are platform specific echos.
Oh but you can. I just try to make the rules in such a way that most

Anyone who wants to know how to portably read a structure from a file in a
way that will work on machines with different sizes for the integer types,
and *even* work on machines with different endianisms, should look at how the
code in zoo reads the file header structures from *.ZOO archives.

You don't need to write your own operating system just to implement a turnkey
system.  Most PC operating systems provide turnkey facilities.
For example, in OS/2 Warp the program that is loaded and run once the
operating system kernel itself has finished initialising is specified by the
PROTSHELL directive in CONFIG.SYS.  This can, of course, be set to anything
one wants, including a turnkey application.  (By default, it is set to
PMSHELL.EXE, the Workplace Shell, which displays a graphical user interface
with a desktop, objects, and so forth.)

Write your reply.

assistant: Actually, the Amiga system API, with function names like OpenDevice(),
InitSemaphore(), and CloseLibrary() very closely resembles Win32 in this
respect, which has names like CreateProcess(), CreateFile(), and
FreeLibrary().  I myself happen to think that that sort of API nomenclature
is far too intrusive into the user namespace, since *I* want to be free to
write my *own* functions called "CreateFile", and prefer the OS/2 style which
prefaces all system API calls with a prefix indicating the particular
subsystem that they are a part of -- thereby placing them in a less central
part of the namespace.  Hence in OS/2 we have DosStartSession(), DosOpen(),
WinCreateStdWindow(), WinSendMsg(), GpiCreateBitmap() and so forth.
Hungarian notation is not actually necessary for programming in either Win32
or OS/2, although the system API references for both are full of it.  I don't
happen to think that Hungarian notation is either necessary or good coding
style either, but I can quite happily write OS/2 programs without it.
No, but you use doubly-linked lists all over the place, which means that your
objection to OS/2 and Win32 ...
... also applies to the Amiga.  Doubly so, as it were.  (-:

Write your reply.

assistant: Borland has only ever had overlays for DOS.  Phar Lap implemented DLLs in its
TNT DOS Extender, which can be used with several 32-bit DOS C/C++ compilers,
such as Borland C++ 4.x/5.x, Microsoft C++, Watcom C++, and MetaWare High
C/C++ for DOS.
Not true, I'm afraid.
DLLs were first introduced to the world of the IBM PC in OS/2 1.0, back in
1987.  Windows took the idea from OS/2, since it was developed *after* OS/2
1.0 was -- which is why Windows uses the same "New EXE" executable file
format as OS/2 1.x, and why OS/2 is indicated by a 1 in the operating system
ID field and Windows by a 2.
The fact that Windows was developed as a "cut down OS/2" by some programmers
in Microsoft who thought that they could be really k00l and develop a cheap
and simple GUI to run on top of DOS using Microsoft's existing DOS extender
and bits and pieces stolen from other products is also why the DLL mechanism
in Windows is not "complete" when compared to that of OS/2.  (OS/2 allows
16-bit DLLs either to be shared by all processes or to have individual
instances for each process.  Windows only allows 16-bit DLLs to be shared
across all processes.)
So no, DLLs, as known in the world of the PC, were *not* technically first
invented on DOS.

ISO 7149:1990 (Specification for programming language Minimal BASIC) and ISO
IEC 10279:1991 (Information technology. Programming languages. Full BASIC.).
The difference between BASIC and C/C++ highlights an important point about
standardisation: it is enforced by market forces alone.  If customers don't
demand standards-conformant implementations from the language vendors, then
they won't get them.  This is something that C and C++ programmers should
bear in mind when they next buy a compiler, lest they find their languages
going the same way as BASIC.
