Tutorial: How to put inline assembly functions into ZX Basic

[LCD]

Ah - then you'd need one that just looks like this, I think:

Code:

function fastcall mirror (number as uByte) as uByte
asm
   ld b,8
   ld c,a
   XOR A
mirrorLoop:
      RR C
      RLA
DJNZ mirrorLoop
end asm
END FUNCTION

I haven't tested it, mind. Just typed it here. Feels right, though

Works and is very very fast!!!
Simple but great!
