Yes and no - the "official" NOP is xchg ax, ax because that's encoded in
one byte instead of the two bytes occupied by mov ax, ax.  However, both
are NOPs in the sense that neither has any effect on the state of the
machine (except of course changing the IP).  But then you doubtless
already knew that, so there's no real disagreement over the effects,
only (at most) over the terminology.

:::sigh:::
It can (apparently) support a wide variety of instructions/directives.
However, it's first being developed as an 80x86 assembler. The idea is
that it can be assembled for a wide variety of >80x86-based< platforms
and operating systems, or even as a back-end for other languages or
compilers.
As I recall the documentation explained it all very well. You've got
InterNet access -- hop on over to Finland or a Simtel mirror or
something and grab a copy. It's worth the look-see. I don't know what
the latest version is but I think they're being archived under the

vironment?
Sorry about this *FAR_TOO_LONG* quote, but I felt it was neccessary to keep
al the info in...
I think, Mikko, that Kevin wants to add a variable to the environment,
which's contents are defined by the ASM program. As long as the program
hasn't run yet, you don't know what the contents of the variable must be.
Thus setting the variable beforehand would be out of the question...
Actually, Kevin seems to need the inner workings of the SET command,
implemented in his program, in order for the program to SET a variable by
itself, thereby allowing him to let some other program work with the result
in this variable.

The task is to shift dx and ax left by 9 bits.  The trick is to make the
high-bits of ax carry over into dx, whereas they would normally be lost.  In
my code, dx is shifted immediately.  AX, however, must be manipulated, so it
is first saved on the stack with "push ax".  Then, I shift AX right by 7
bits, thus PRESERVING the 9 highest bits in the lower end of the register.
AX now serves as a bit mask and ORing DX with AX puts the formerly high bits
of AX into the low end of DX -- filling the gap left by "shl dx, 9".  AX is
then restored from the stack and shifted left 9 places.
I hope this helps.

Method 1: Using Extended Register (result in EDX)

        mov dx, ax          ; put ax into the low word of edx
        shl edx, 9          ; shift edx (DX:AX) left by nine places
Method 2: 8 and 1 Shift (8086 compatible)
        mov dh, dl          ; These four lines shift DX:AX left by 8 bits
        mov dl, ah          ; simply by switching the bytes around.
        mov ah, al          ;
        xor al, al          ;
