Thank you for your feedback. Three final words.
a) provided stack is 4 bytes large, your program is better managing his own
stack as does the latest version of your "hello world" sample,
b) zbrun at init time will complain if a transparent address map Z80 soft
card is detected. Provided doc files give details upon the CP/m friendly
translation address map (offset of 0h1000 bytes between 6502 and z80
visions)
c) your program origin could be anywhere (not only 0h2000), beware not to
crash any AppleSoft, or dos 3.3 locations through.
Regards,
Benoit
