Please, try again; there should be no problem at the moment.

I guess that this setting is there because most XCode users are expected
to know the older Pascal compilers for MacOS and thus used to the macpas
syntax / features.

Different modules (units and the main program) may be compiled in
different modes. This means that you can use Carbon framework (accessible
via unit MacOSAll compiled in MacPas mode) in programs / units compiled in
fpc or objfpc mode.

Yes, it will.

I don't feel confident enough to answer this (or the more detailed
questions from your e-mail) because I've never used MacPas myself,
although I believe that your findings are mostly correct.

Well, yes, your message came as "multipart/alternative", i.e. including
both HTML and plain text versions.

I suggest to file a bug report pointing out the necessary improvements in
