Write your reply.

assistant: To understand ASSUME directive, think of your program existing in two
dimensions.  The first dimension is assembly-time--the actions that
occur when the assembler assembles the program text.  The second
dimension is run-time--the actions that occur when COMMAND.COM loads
your program into memory and executes the first instruction.
The ASSUME directly belongs strictly to the assembly time dimension--it
has no effect on the program at run-time.  Use the ASSUME directive to
tell the assembler that segment registers such and such address segments
so and so.
By using ASSUME, you give the assembler the ability to perform two
actions:
- Verify addressability of variables in data segments
- Add segment overrides automatically as needed
The second of these advantages is most important.  By using ASSUME, the
assembler can insert an es: segment override instruction, et cetera.

Write your reply.

assistant: To fully enable the the UART's interrupts, the computer's 8259
Peripheral Interrupt Controller (PIC) must be set to recognize the
UART's interrupts.  Once it is set up to recognize the UART's
interrupts,  the 8259 will generate an appropriate CPU interrupt.  Thus
the CPU will halt its current task and call the desired Interrupt
Service Routine (ISR).
To set the PIC to recognize the UART's interrupt, the program must
enable the appropriate IRQ line in the PIC's Interrupt Mask Register
(IMR).  The IMR is addressed by either writing to or reading from port
21h.
After processing or ignoring an interrupt, the ISR must re-enable the
8259 PIC.  Whenever an interrupt occurs, the 8259 PIC will continue to
recognize interrupts, but it will not tell the CPU that another
interrupt has occurred until an End of Interrupt (EOI) command has been
written to the 8259 Interrupt Control Register (ICR).  The ICR is
addressed at port 20h and coincidentally enough an EOI command is equal
to 20h.  Consequently, the program should always write an EOI to the ICR
before it returns control back to the CPU.

There is an ASMEDIT program which I saw some years ago that worked
nicely with Turbo Assembler.  You could actually assemble your assembly
code within the editor.  Any assembly error messages that were found,
the editor would place you at the given line; similar to Borland's IDE

    1) When you are trying to avoid CALL/RET overhead
    2) When you need to use assembler directives like ".type" to return

assistant: Hi Josh!
       That's what I was referring to.
       Hmm...that's interesting.  Although, since you are using EBX instead
of BX, that would assume that your array can exceed the confines of BX, or
64k of data.  Can this be done with 16-bit code?
       Not to me it isn't.
       That's what I was saying.
       I don't see why you think that I wanted MASM compatible code.  I never
said that.
       It's expensive.
       I believe NASM also allows you to use the override segment as a
prefix:
       es mov ax, [label + 1]
       Really strange syntax.

       No..I wasn't talking about BASIC, I was using it to prove a point.
       Remember?  We're not talking about BASIC.
       I did it to show the different between BITWISE and LOGICAL.  And
hopefully, this will be recognized.
       From what I've seen, ASM doesn't have LOGICAL operations, only
BITWISE.
       If you go about it LOGICALly, then 10010110 AND 01100101 would be
TRUE.

=Ted Menks babbled to Nick Coons about 486 MOV.=
How can it execute an NOP (or anything for that matter) when the
processor is asleep waiting for the completion of a bus cycle?  The
wait states are generated by hardware on the motherboard.  What happens
during a bus cycle is (simplified), the processor puts a port or memory
address on the address bus.  Then it signals that a valid address is on
the bus (in the case of the 80x86 it indicates what type of address it
is).  Then the processor waits a few clock ticks for the device to put
data on the data bus.  Before accepting the data, the processor checks
an acknowledge line.  If this is not asserted, it waits a clock tick
and repeats.  Some devices (such as DRAM) cannot respond fast enough
and the controller must delay the assertion of DTACK.  This is called a
wait state.
With a 200 MHz processor and an 8 MHz bus, an NOP is a shorter pause
than a wait state :)

Here we go again! ;-)
(Sunday February 23 1997 11:52) Nick Coons to Ted Menks about: 486 MOV.
Well, if we start talking BASIC, we're way off from the ASM-topic, don;t you
think? Anyhow, the way in which BASIC handles the LOGICAL operators, is not
quite homogenous. Neither is it the same for all BASIC-dialects.
With SOME BASIC's this is exactly what happens, but I've also found some of
them that would combine the 1 and 2 bitwise, and really find the result to be
0. When such a thing happens, one had to write:
IF ( 1 <> 0 ) AND ( 2 <> 0 ) PRINT "Hello Nick, you're off!" ;-)))
I've had both kinds of BASIC on hand, the "1 AND 2 = 0" type would be found
on the AMSTRAD CPC-range of computers as well as the Sinclairs...
Therefor I think BASIC is not quite the best example you could have taken,
since it is available in so many different flavors.
In ASM however, the BITwise AND the LOGICAL operations are the same thing.
10010110 AND 01100101 would be 00100100, whether you would go about it
logically or bitwise. ;-))
