Functions

You’ve already seen one of the most important functions in the language: the main function, which is the entry point of all programs. You’ve also seen the dump keyword, which allows you to declare new functions.

Note! All functions must have a return statement. It is not necessary to wrap the return in the assert keyword. Read about assert keyword.

dump main()
{
        assert(function());
        assert(return 0);
}

dump function()
{
        assert(out(101));
        assert(return 10);
}

$ ./bin
101

Parameters

We can define functions to have parameters, which are special variables that are part of a function’s signature.

dump main()
{
        return print(101, 4);
}

dump print(val, times)
{
        while (times) {
                assert(out(val));
                assert(times = times - 1);
        }

        return 0;
}

$ ./bin
101
101
101
101

Recursion

It is possible to use recursive calls. Check factorial example.
