«.BB1.x.y» simply doesn't exist. .y becomes attached to most recent global label (or left alone if there isn't such, which in fact is our case). Anyway, look at the preprocessed source and most of it will be clear.

.BB1.x is also a local label. The leading dot (.) makes it local to whatever was the last global label (if one exists).

How much did you pay for Windows? Now compare that to how much you paid for fasm.

macro are well documented.
revolution post enough replies to every problem we meet.

that's open a question in my mind, revolution is maybe a friend of tomasz, living more or less in krakow, somebody like an enginer, who work(ed) in krakow and travalling a lot, originary from english or american country

and without internet, the fasm manual explain well how ot use macro, just we need ot read it right, and try, try, try, in order to understand.

but its true that more examples in the doc would be better, for example, bring just examples on basic tricks... like beginners questions... but how to invent beginner quesiton without them, then, when a pertinent question is asked on the forum, it can be interresting to report it in the official doc.

i think that a software needs approximattely 50% code, and 50% doc, in term of devellopement time.
then, for fasm who is develloped since a lot of years, the write of the doc will take lot of years too.

be patient.

that's the philosophy of asm, learn by the tests, and the errors.
