It could be fun to compare with Action!--it's been known to compile a reasonably good 6502 assembly (considerably better than other compiled languages for that platform), https://en.wikipedia.org/wiki/Action!_(programming_language),

It has been released as open-source together with the binaries, https://atariwiki.org/wiki/Wiki.jsp?page=Action

You should be able to run these using an Atari 8-bit (XL/XE model) emulator, like Atari800, https://github.com/atari800/atari800/releases or Altirra, https://www.virtualdub.org/altirra.html
