Functions

Functions are procedures (custom blocks) that can return values (or structs). Functions are always Run without screen refresh and must be only called within Run without screen refresh procedures or functions to prevent undefined behavior. Functions must always terminate with a return statement. Using stop_this_script inside functions is undefined behavior.

Declaring a function

func my_function(x, y) {
    return $x + $y;
}

func my_function(x, y) type_name {
    return type_name { ... };
}

Calling a function

say my_function(1, 2);
