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!
