use the FASM, make a program.
but emerge a error.


my declare is '._Leave'.

is '?Tz' Come from?

Thanks for answering.

You declared "._Leave" label as "local" in some macro. FASM adds unique suffixes to the local labels in order to resolve possible conflicts.
As a rule, such labels are only for internal use in macros, not from the user, because you can't know what suffix will be added.

I understand, thank you! ^_^
