Well, so many examples are enough for start to anyone. It's time for me to dive into chess programming 

will you use Millfork for the chess program?

[zbyti]

@ilmenit definitely! However, during converting your landscape ASM code and checking what optimization I get I'm quite aware of the Millfork limitations compared to ASM.

I will probably write the first program in Mad Pascal also, to see what I can get from @tebe work.

const word ADDRPLA = $b000

byte stop @ ADDRPLA + $62d

asm void takt() @ ADDRPLA+3 extern

  comm(0,ADDRMUS.hi,ADDRMUS.lo)

Yup. Millfork seems to be one of a very few true 8bit languages. Integer promotion to 16bit for arithmetic in other languages and has huge performance impact and is very hard to control either manually or by optimizer. Millfork's manual type conversion looks great, but can be confusing for users of other languages
