Loops

orbit controls iteration in AbySS. Pair it with resume and eject for fine-grained flow.

Simple Range

orbit (i = 0..5) {
    unveil(i);
}

0..5 is half-open; swap in ..= for inclusive bounds.

orbit (i = 0..=10) {
    unveil(i);
}

Infinite Orbit

Omit bounds to loop forever and break with eject.

forge morph i: arcana = 0;
orbit {
    oracle (i == 100) {
        (boon) => eject; // break
    };
    i += 1;
};

Multiple Induction Variables

orbit (i = 0..3, j = 0..3) {
    unveil(i, " ", j);
}

Flow Control

• resume <loop-var> skips to the next iteration of the named loop.
• eject <loop-var> breaks out of the specified loop.

orbit (i = 0..3) {
    orbit (j = 0..3) {
        oracle (i == j) {
            (boon) => resume j;
        };
        unveil(i, " ", j);
    }
}

orbit (i = 0..3) {
    orbit (j = 0..3) {
        unveil(i, " ", j);
        oracle (i == 2) {
            (boon) => eject i;
        };
    }
}

resume and eject understand nesting, so you maintain readable flow even in complex rituals.
