how can running x86 code inside 64-bits process?

[mldonkey]

how to use this macro?can you give a sample? `X86_Start MACRO LOCAL xx, rt call $+5 xx equ $ mov dword ptr [rsp + 4], 23h add dword ptr [rsp], rt - xx retf rt: ENDM

X86_End MACRO db 6Ah, 33h ; push 33h db 0E8h, 0, 0, 0, 0 ; call $+5 db 83h, 4, 24h, 5 ; add dword ptr [esp], 5 db 0CBh ; retf ENDM`

That is a good question, an example for the less experienced would be nice.
