As some may already have notice, I love to port things to my Atafri. This one is obviously inspired by sierp2 of course. Thanks to Ruelle, I really love this kind of mathematical beauty.

Note: Atari's executable format leaves you with 26 bytes of code for this ;-)

Code: * = $2000 start lda #8 ;Graphics 8 hires mode jsr $ef9c ;Illegal entry point in REV C OS, returns with C=1 loop ldy #0 ;Current line lda (88),y ror ;Rotate into carry bit eor (88),y ldy #40 ;Next line sta (88),y inc 88 bne loop inc 89 dec $53 ;RMARGIN is initialized to 39 by the OS bne loop ;There will be BRK, so the system will stop

Had pb with running but considering it is 32b (26b without execution rules) and still running I can say - congratulations.

Cool! It makes me happy to see that my sierp2 is helpful for other coders.
