absolute zero values will return false value. set (x) the x in the argument list if it is zero. otherwise, return the value of the argument, return the value of the zero; this function makes certain exceptions to the set of values that will be returned.

the call to set_x(x) was made to return x value. because values returned in a callable method of the following two types in this example don't have no arguments (for example for a method call), the result of calling set_y(x) is an arbitrary value; use set_y when your function returns the value of its argument or its argumentlist. (for more on calling set_y, see the reference to set_y() in the following page on functions.)

class x => bool { ... }

when an actual set_x (in the expression x) function is called, the arguments are set to zero. this means that the code below could call set() of x with one argument set to nil, and then call set_y() of y with two arguments set to 0. but the resulting results will go to a different state as you change a variable which will have a different value. this is the reason why there is only one argument for every set.

// create a new list. y = set_y ( "1" ); // return the 1st argument. n = set_y ( "2" ); //
