See $LK,"::/Compiler/OpCodes.DD"$ for opcodes.	They're not standard.  Some invalid insts are not flagged and some valid insts are not implemented. 16-bit asm support is limited.

Here are example instruction formats:
$HL,1$		ADD 	RAX, I64 FS:DISP[RSI + RDI * 8]
$HL,0$$HL,1$		ADD 	RAX, I64 [DISP]
$HL,0$
$FG,2$$$$FG$ Current compiler output pos (instruction pointer).	Even works in ZealC expressions.

$FG,2$$$$FG$ works in $FG,2$class$FG$es.
	$FG,2$class MyFun
	{
		$$ = -16;
		I64 local1;
		I64 local2;
		$$ = $$ + 256;
		I64 crazy;
	};$FG$

$FG,4$LABEL$FG,2$::
$FG$	Defines an exported global label.

$FG,4$LABEL$FG,2$:
$FG$	Defines an non-exported global label.

$FG,2$@@$FG,4$LABEL$FG,2$:
$FG$	Defines a local label with scope valid between two global labels.

$FG,2$DU8$FG$, $FG,2$DU16$FG$, $FG,2$DU32$FG$, $FG,2$DU64$FG$
	Define BYTE, WORD, DWORD or QWORD. Can be used with $FG,2$DUP()$FG$ and ASCII strings.	For your convenience, the ASCII strings do not have terminating zeros.	Define cmds must end with a semicolon.

$FG,2$LIST$FG$, $FG,2$NOLIST$FG$

$FG,2$ALIGN$FG$ $FG,4$num$FG$, $FG,4$fill_byte$FG$
	Align to $FG,4$num$FG$ boundary and fill with $FG,4$fill_byte$FG$.

$FG,2$ORG$FG$ $FG,4$num$FG$
	Set code address for JIT or set module $LK,"Load",A="MN:Load"$() address -- has 16-byte $LK,"CBinFile",A="MN:CBinFile"$ header and patch table trailing.
