Yes!
It seems faster, yes, but things such as cache, instruction overlap etc.
should also be taken into account.
Er... I don't know, I've always used LOOP. LOOP is AFAIK assembled as
LOOPZ (LOOPE the way it should look :-).
Well, something named a prefetch-something takes care of that along with
the cache.

Well, it has been every time I've tested it.
Hmm... could these be the remains of some truncated sentence written long

No, these would overlap the move operation, just as the first two (three :)
instructions would overlap if AX wasn't used in both.
In what way?
Anyway, it can not be _more_ flexible than your own example above.
That should be the least of your worries, shouldn't it? :-)

of extra segment registers for no reason other than they felt like it. You
can use them yourself as you like - there is no "special" system use of them
(unlike CS, DS & SS). Most assemblets for 386 fully support FS & GS.
They're only available on 386+ CPU's though.

Write your reply.

assistant: I'd hardly call it a cop out.
Your original post was just asking about doing serial I/O.  That
generally implies drivers that would work on all/most uarts, with and
without the FIFOs enabled, detecting and working around bugs in some
versions of the UARTs, and so on.
And since there are such a wide variety of controllers and situations
that you would have to deal with, it becomes a lot of work in writing
it, debugging it, and maintaining it.  That's why it's better to let
others do it.  They've already had to go through all that.
Your message didn't say it would for a very specific use with a single
controller.
Well... There are a few more things.  Like dealing with the FIFOs,
making sure your uart even has a FIFO, setting up for the serial I/O
interrupts, etc.

Write your reply.

assistant: You should make all demo effects (especialy slow 3D stuff) a function of time
..
read the PIT directly with soemthing akin to..
    sub al, al
    out 43h, al    ; latch timer 0
    in al, 40h     ; LSB of timer 0
    xchg ah, al
    in al, 50h     ; MSB of timer 0
    xchg ah, al
the PIT counts down (by default) from 65535 with an increment of 2
You should (at least) reprogram the PIT to count by 1..
    mov al, 34h         ; counter 0 / word / (mode 2) count by 1 / binary
    out 43h, al
    sub al, al          ; reset counter 0 and use new mode
    out 40h, al
    out 40h, al
..now, the PIt is a fast beast.. it will chew out 65536 "ticks" every 1/19th
of a second .. using up its 16-bit resolution .. so you will need to keep
track of these 1/19ths (or let DOS do it)

Write your reply.

assistant: Hello Moderator, my 2 cents...
    In general it is. This echo is an exception. :)
    Another reason to cover it in the rules.
    I used Lha because in another echo it was recommended because it's free.
    However, I believe the use of pkUnzip is also free.
    When using UUE, do you encourage the use of the -x option? (xxe)
    IMHO, file_id.diz are a real convenience to organizing files.
    I don't see it as a BBS issue.
    When compacted in the zip it may add 25-300 bytes.
    Without it, all that text has to be put in the sourcecode.
    Well, it may be there anyway, but I use the diz to make a descript.ion
    automatically, so I find a diz valuable.
    Sorry about including the .com file. That was a mistake.
    Hope you continue as moderator, James.

assistant: Hi Denis
 You right i think. It may be set to zero few lines of code before it reachs
 the IRET (if interrupts are enable) and exit from the DOS interrupt.
ifferent
  Yes i could, but need the check anyway critical flag otherwise the program
  will crash. So isn't good call DOS within DOS itself? :>
  Here is a part of a DOC about DOS interrupt
        INT 20  Program terminate
        INT 21  DOS Function Dispatcher
        INT 22  Program Terminate
        INT 23  Ctl-break exit address
        INT 24  Critical error handler address
        INT 25  Absolute disk read
        INT 26  Absolute disk write
        INT 27  Terminate but stay resident
        INT 28  DOS idle loop/scheduler (undocumented)
        INT 29  Fast character output (undocumented)
        INT 2E  Execute command using base level COMMAND.COM (undoc.)
        INT 2F  Multiplex interrupt (DOS 3.x+)
 Does it mean that inDOS flag isn't own by INT 21h only? But throught this
 range?
 But after printing on indos=1 i get this when i type to the prompt.
Intermediate file error during pipe
So the command line becomes messy.
  Okay, i will grab them and try it.

Write your reply.

assistant: Hello Brian ...
Hmmm ...
I think you know (since Taylor said it long ago!) that each continuous
function (which is derivable in the open segment considered, but that's the
case for the function you ask!) can be represented by its Polynomial forms.
For ex. :
exp(x)= sum for i=0 to infinite of (x^i)/(i!), with
0!=1 and x^0=1 too.
That can be expressed as :(with eps = precision required)
sum=1+x;
factor=x;
for(i=2;fabs(factor)>eps,i++)
  {
   factor=(factor*x/i);
   sum+=factor;
  }
(I tried to make it in asm, but my knowledge of x87 is a bit short!)
and
cos(x)= sum for i=0 to infinite of 1+(-1)^i*(x^(2*i+1))/(2*i+1)!
sin(x)= sum for i=0 to infinite of (-1)^(i+1)*(x^(2*i))/(2*i)!
