15 bytes implementation of the famous C64 BASIC one-liner program:

Code:10 PRINT CHR$(205.5+RND(1)); : GOTO 10

My implementation is trivial. There must be a few bytes to gain.
Come on! THREAD OVER reached 12 bytes on C64

why not :)

wow nice trick

Using int 0x29 to output
and something like
;randomly set c flag
salc
and al, '/'^'\'
xor al, '/'
is a way to save some bytes.
But isn't it better to make more interesting labyrinth?
Square or or hexahedral or so :)

There's already a 10 byte version, check the link in the comment section of Thread Over :)

Fuck yeah

Cooool

Great. What about doing it 13h mode ? (will require a few more bytes, but not that much)

Wow brilliant!

britelite: Oh thanks! Why didn't they submit it to Pouet ? I think it's totally worth it and legit. So cool ideas.

I didn't want to go the scasb road: It saves 2-3 bytes but kills a lot of the randomness. In my mind my 15 bytes version was more like the 12 or 13 bytes versions of the C64.

frag: Thanks! My x86-fu is super rusty; my little memo of the x86 instruction set doesn't include the "undocumented" instructions or interrupts like salc and int 29h. Do you have an online resource I could use ?

I was looking for an inst like salc, but my memo only had setc, to do something like

Code:

and al,'\'-'/'
add al,'/'

of the 10 bytes version by Peter Ferrie.

You guys rock!

Where brilliant means: Wow! That's exactly what I was hoping for: To learn a few tricks and see more takes on this seemingly simple program.

ANd AL,'\'-'/'

aaa

nice christmas gift!

sweet! back then, coded a "real" textlabyrinth, with backtracking, in Pascal i guess. Maybe i do a asmrerelease ... or simply dump the code here if i'm too lazy ^^
