Using Turbo, I get the following results for the code below.  If everything
was promoted, resultf would be the same as resultfi.  An interesting result
from 30000 * 30000 though.
resulti -17664
resultf -17664.000000
resultfi 2700000000.000000

int main(void) {
int a = 30000, b = 30000, multii = 3, resulti;
float multif = 3.0, resultf, resultfi;

assistant: When you apply a bit-wise operator to a variable, ALL the bits are
affected (not just the subset of bits which hold your interest).  This
looks correct to me.
The left-most bit (bit 0) holds the sign of a number (in this case, an
int).  Flipping it as you did changes the sign from positive (0) to
negative (1).

    No. Back to basics. A 1 in the MSB of any signed representation makes it
negative. Numbers are signed by default.
    If you want the decimal representation of it as an unsigned number, try
treating it as one, as in this example using unsigned longs:-

    In a message from Bob Tailor to All
    on 26 Feb 98  11:03:41 about hi
    you said:-
    An array doesn't *do* anything. An array *is* a list of objects, like
numbers or characters or pointers or arrays or structures. It *has* a name.
It *has* subscripts which allow you to access any element of the array. The
unsubscripted name of the array is a pointer to the first element of the
array. Arrays can also have dimensions.
    Sorry if that's more than you wanted to know. Most books on C demonstrate
and explain arrays quite well.
Best wishes,
Bill.

assistant: Hi Alan,
You wrote to me:
That's overflow in the integer calculation...
I changed it to:
float resultf1;
resultf1 = multif * a * b;
printf ("resultf1 %f\n,resultf1);
and with BC 3.1 got :
resulti -17664
resultf -17664.000000
resultf1 2700000000.000000
resultfi 2700000000.000000
Which is bad news, as obviously the Borland parser only does the
conversion to float when it encounters one in the source stream. afaiaa
this is not strictly ANSI compliant, as rearranging the order should not
change the result. Hopefully one of the experts with a copy of the
standard will check this for us.
I've checked BCOS/2 V1.0 and it gets 2700000000.000000 for resultf
(probably, it certainly gets that value, but crashed on the output :-(
).
IBM Visualage C++ V3 also gets the correct value.
These results don't change if the int declaration is changed to short.
So, as far as I'm concerned, the Borland compiler you've got & my BC 3.1
both have faulty parsers in this case and my understanding of the rules
still looks correct
George

IMHO ... this produces a function that is used as interrupt code. That is, it
first saves the processor registers it may modify and in the end it restores
then and exits with the <return from interrupt> instruction which probably
restores processor flags and loads the pc/ip with the address to continue the
interrupted program.
While being in interrupt at least the interrupts of the same and lower
priority must be disabled. Otherwise if you - say had to receive and process
bytes from the serial port you usually want to complete you ISR before it is
called upon the arrival of the next byte. This is also the reason for that
you should keep ISR short (in time) eg. just dump the bytes into a buffer and
leave further processing like displaying them on the screen to non ISRs.
You must probably hook you ISR to an interrupt then the ISR will be called
every time the interrupt occurs. So you don't wait within the ISR. Look for
functions like setinterrupt() and check the examples.

assistant: Where can we obtain a copy?
Isn't the general consensus that C++ is a (better) extension to C, but we
are truely programming in ++ when we start using the class structures?
also, how do we know which is C and which is C++, My compiler will allow me
to use C only (via the .c extension option for files), but I cannot tell it
to use C++ only, which (I think) the Linux compilers require.
Does the Standard say that any C command is legal under C++???
Also can anyone please give me a List(if such exists) of the Borland
specific header files / functions so that I can avoid using them.

Caldera's OpenDOS offers it's source code for free for non-profit uses. You
can find their site on the internet at www.caldera.com.  Seems they've
changed the name of OpenDOS back to DR-DOS.  Latest version seems to be 7.02.
The source code makes for nice reading.  Another plus is that it doesn't
depend (much) on compiler libraries, so it includes a lot of raw source code
for standard library functions (such as printf())...
Hope this helps out.

 I could remove whatever I did not need and have it start my C program.

 Is C once it is compiled as a dos program looking for MS DOS or is most
 any dos compatable or does the maker of the DOS clone maker have to keep

AHA! Brain lock would not let me consider the extra varible "v".

Your correct about the code although the following all give the correct

e = ( (v) >> 0 & 255 );

I think this has become only an exercise and not useful. I have a
system call that will send a signal to a process ID. I had wanted
to send information to a process running in the background. After
studying the docs on the system call 'fsend' I find it will only send
information of length WORD, 16 bits.
Would have been nice to drop 4 bytes of information through 4
switch statements at one time.
Well back to the drawing board. Its time to let this thread end.
