Ok. I've readed 2 books and god knows how much material on the net about assemly programming, but I have never came across text explainig why some people put @ and @@ before jump labels. Could anybody explain that to me?
PS. maybe I'm just so stupid...

Well, I know that @@ is a local label you use when you don't want to put a name to it...
However I have no idea of why some labels have a name, and begin with @ and @@... I'd be interested in the answer too :grin:
cmp eax,1
je @F ;this jumps FORWARD to the next @@
; do some stuff...
@@: ;more stuff...
cmp eax,2
je @B ;this jumps BACKWARDS to the previous @@However I have no idea of why some labels have a name, and begin with @ and @@... I'd be interested in the answer too :grin:
NaN: Thanks for the link :)
Still, how come sometimes I see labels like this?
Why the @ and @@ in the beginning of the label name?
:confused:

If others are like me... Then, it is completely a habitual thing. :)
I create local labels (visible only inside a file) prefixed by '?' so that I know it is a local thing when I read it later. Some people prefer '@', and others have their own rules.

Hi QvasiModo,
Anything ending in a single colon (:) is a local label i.e.
lable: ; is local
for global labels in MASM you must use a double colon (::)
lable:: ; is global

Since we are on WTHs
why are some people just crazy with underscores?
_myvar
my_long_ass_blahlah_blah
its ugly as hell :)

It more readable than MYLONGASSBLAHLAHBLAH
I used mixed case:
MyLongAssBlahBlah
MyLongAssBlahBlah
right on! :alright:
I think all variables show actually say something too, like:
Like WindowHandle instead of hWnd.etc..
I used hungarian notation at one time and grew sick of it.
EDIT: I'm happy, two people typed ass not in anger! lol

Thanks for the tip, donkey! :alright:

So do I, I think it's more descriptive. But I always end up with the bad habit of using @1, @2, @3... just because I'm a lazy programmer. :grin:
For me its mainly cause of its name "At".
ie. jmp @Error
"Jump at Error" (its how my mind 'says' it while programming).
:NaN:

I think @@ prefix is a habit whom used to tasm. Because it's already assumes(if any other prefered) @@ is a local variable where prefixed. Nowadays most people using masm32 and it has a @@ as a different purpose but not a prefix. Anyway, if this is not a habit from tasm usage, then it is nothing, meaningless, decoration, i think so.

Anonymous labels are good to have, but I find myself moving away from using them and I like it better. :)
since i do lots and lots and lots of loops
mine are normally named LoopA LoopA_1 LoopB_1 but i think loopd is one im not allowed to use lol...
but this helps me when im translating files and lets me know what step im at...
