Control Flow

ROX provides minimal but sufficient control flow constructs. All control flow is explicit.

Conditionals

if / else

Standard conditional logic. Boolean expressions must be explicit.

if (x > 10) {
    print(['B','i','g','\n']);
} else if (x == 0) {
    print(['Z','e','r','o','\n']);
} else {
    print(['S','m','a','l','l','\n']);
}

Loops

repeat

ROX has a single loop construct: repeat. It iterates over a range of numbers.

Syntax: repeat var in range(start, end, step)

• start: Inclusive
• end: Exclusive (stop before this value)
• step: Increment amount

// Print 0 to 4
repeat i in range(0, 5, 1) {
    // i is 0, 1, 2, 3, 4
}

To iterate backwards:

// Print 10 down to 1
repeat i in range(10, 0, -1) {
    // i is 10, 9, ... 1
}
