Write your reply.

assistant: Hi Ian!
       The difference being that bitwise functions simply look at the bits of
a number (or two numbers) and act accordingly.  Logical functions check to
see if a value is TRUE or FALSE.  Since OR, AND, XOR, and NOT (is NOT used in
ASM?) are all bitwise functions, they simply look at the numbers and set the
bits.
       The best way to demonstrate logical operators is to use real-life
situations.  Let's say your father asked you, "Did you take out the trash AND
do the dishes?"  If you did both, then you would answer, "Yes."  If you only
did one or neither, then you would have to answer, "No."
       Maybe I can use a BASIC statement to illustrate logical:
       IF a% AND b% THEN ....
       BASIC determines a value to be TRUE if it is nonzero.  If a% is TRUE,
and b% is TRUE, then do the stuff after THEN.
       Hope that helps...

=Nick Coons babbled to Kevin Barrow about 486 MOV.=
One clock.  The point is usually to put the NOP as a place holder.  For
example, when a single pass assembler such as TASM encounters a forward
jump, it will insert 5 NOPs and go back and fill it in with the
appropriate opcode and operands when it resolves the address.  If it
was not a FAR jump, there will still be NOPs there, but they won't hurt
anything.  Running in multipass mode will allow TASM to strip out the
extra NOPs.  NOPs can also be used to remove functionality from a
program without inserting any instruction that would modify registers,
data, or flags.  One common cracking method is to insert NOPs over the
copy protection code.  It does have legitimate uses, primarily in
debugging and self-modifying code.  For example, if you were debugging
a program, and it called a routine that was not necessary for execution
and you didn't want to debug through it, you could replace the jmp or
call with enough NOPs to cover up the opcode and its operands from
within the debugger.  Even though it does nothing, it can be quite
useful.  The "official" NOP is 90h, which is the opcode for "xchg ax,ax".

Write your reply.

assistant: Hi Gary,
    CS = Code segment
    DS = Data segment
    ES = Extra segment (called that, because String segment would
         cause a conflict with SS)
    SS = Stack segment
    FS = ??
    GS = ??
    Viewed in that manner I'd easily enough accept logical sounding
names for FS and GS, although that doesn't necessarily imply they have names.
The first three segment registers appear to fit both the explanations
perfectly
well but one thing strongly against the "following the alphabet" argument is
the lack of AS and BS. That's not to say that the same applies to FS and GS
of
course.
    Exactly the same logic can be applied to the offset registers.
There appears to be a simple following of the alphabet, until we get to BP,
which I'd overlooked in my previous message. :-(

Write your reply.

assistant: Hi Hugh,
<Snip>
    A86 will assemble source such as that to a COM file unless told
otherwise. This is the way it's intended, rather than a bug. To create an EXE
file you need to tell A86 to assemble to an OBJ file and then run your linker
over it. The result will be an EXE file. TASM also does it that way, although
the process is (I'm guessing) transparent to you. I hazard a guess that TASM
calls the linker itself, so that you don't have to do that part manually.
There
are arguments for and against both methods.
    To avoid trying to remember the correct command line switch to
use when assembling to an OBJ file just use the "to" switch. e.g. "A86
test.asm
to test.obj". That's a lot easier to remember, especially if you don't use
he
program a lot.
    Personally, unless you absolutely *must* have an EXE file, I'd
go for the more compact COM file anyway.

Write your reply.

assistant: Hi Nick!
It shouldn't if you have the DB 66h over-ride because you would be shifting
EAX not AX. Since EAX is a 32 bit register the bits should shift over from
AX into the high of EAX. If you didn't have the over-ride, then you're
correct, you'd loose those bits.
ie:
    EAX = 0101 0101     SHL 4       EAX = 1010 1010
     AX =      0101     SHL 4        AX =      1010
If DB 66h was used then:
    EAX = 1010 1010
otherwise only AX is shifted, so instead:
    EAX = 0101 1010

I tend to recall something where one might use several NOPs to wait x amount

I would imagine that it was a safe bet when used on the original 808x series
