Assembler

See ::/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:
        ADD     RAX, I64 FS:DISP[RSI + RDI * 8]
        ADD     RAX, I64 [DISP]

$ Current compiler output pos (instruction ptr).    Even works in CosmiC expressions.

$ works in classes.
    class MyFun
    {
        $ = -16;
        I64 local1;
        I64 local2;
        $ = $ + 256;
        I64 crazy;
    };

LABEL::
    Defines an exported global label.

LABEL:
    Defines an non-exported global label.

@@LABEL:
    Defines a local label with scope valid between two global labels.

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

USE16, USE32, USE64

IMPORT sym1name, sym2name;

LIST, NOLIST

ALIGN num, fill_byte
    Align to num boundary and fill with fill_byte.

ORG num
    Set code addr for JIT or set module Load() addr -- has 16-byte CBinFile header and patch table trailing.

BINFILE "FileName.BIN";
