Which setting would that be, I do not know where to change those.

Yes, I have seen that, but I do not know how it is possible that I get those errors.

Flag -92 is set, because I program always in sys-rpl. Assembly is something I hope to learn someday, but is difficult yet, despite the documentation I have.

Most of the code is placed in "CODE" and "ENDCODE" statements, so that should not be a problem. However, the errors are incomprehensive to me.
