assembly offset
As some of the other answers say, the offset keyword refers to the offset from the segment in which it is defined. Note, however, that segments may overlap and the offset in one segment may be different in another segment. For instance, suppose you have , Outside of 16-bit code, on normal OSes, virtual memory is flat, with all the segments having base=0. So it's just a complicated way to say that OFFSET var gives you the address of var as an immediate, instead of loading from it. mov esi, bVal ; load , .data Number dd 3 .code mov eax,Number mov ebx,offset Number. EAX will read memory at a certain address and store the number 3. EBX will store that certain address. mov ebx,offset Number. is equivalent in this case to lea ebx,Number., In x86 architecture, every address has two parts - segment and offset. So, OFFSET means simply that the offset of the address of some variable "Hello_Wo.??_C@_0M@KPLPPDAC@H" is pushed in the stack. This directive is from the MASM syntax where &,Offset” is an assembler directive in x86 assembly language. It actually means “address” and is a way of handling the overloading of the “mov” instruction. Allow me to illustrate the usage - [code]mov si,offset variable mov si,variable [/code]The ... ,As Toby Thain already said, it's usually an amount added to, or subtracted from an address. More generally, it's the numeric distance between two things, expressed in multiples of whatever the addressable units are. This is a generic concept, and ,mov ax , arrayW ; ax = 100h , arrayW WORD 100h,200h,300h mov ax , [arrayW+2] ; ax = 200h ; Direct-Offset Addressing (doubleword array) mov eax , arrayD ; eax = 10000h , arrayD DWORD 10000h,20000h mov eax , [arrayD+4] ; eax = 20000h ○ 加法與減法 ＊零值旗標: 當算術指令將目的, I'm not bad at programming with C++, but I'm new to assembly language.
