Ok !!! Sorry for the mistake...

In my file, I get the error 116 (because of the BIT macro), and gpasm is
talking about pass 1 and pass 2. If I understand, the first one is the
lexer pass, and the second is the parser pass. Am I right ?

Well, I think I will expand this macro manually for the moment. It is not
very hard to do. Take all time you need to make good job.
Thank you very much for the explanations: I like to know how things run...
Many years ago, I wrote a Z80 assembler under Mac. It was working well,
but I didn't use all gpasm features (IF, MACRO, ...). It was pretty
simple. So it is very interesting to understand how *good* assemblers work.
