If I use subleq, I would have to use the value range 0-255, and so instead, I write the bytes in the .data directive to use the - sign so it’s slightly easier to understand. By writing the bytes ‘by hand’ in the .data directive, I also have to handle the jumps, which are normally handled by the assembler.
Example:
subleq @OUT 2 -‘0’ isn’t allowed, but you can subtract from 256 subleq @OUT 2 208 is what it will be, but it’s less expressive So, @prog: .data @OUT, 2, -‘0’ is the best choice in my opinion
