Click the green flag and watch it run - when the maze fills the screen, it scrolls to make room for more. This is a Scratch implementation of the famous one-line Commodore 64 program, 10 PRINT CHR$(205.5+RND(1)); : GOTO 10 To see my music video featuring a 6502 assembly version of 10 PRINT running on a real Commodore 64, search Youtube for "Confounded to Corruption".
Thanks to 10print.org for inspiration, and greets to 2sman for making the first 10 PRINT port in Scratch, as far as I'm aware. Thanks to the Scratch team for the new(ish) ability to make blocks that can run without screen refresh, to allow programs like this to run MUCH faster. I should revisit some of my old games with this new ability...
