Documentation(info = "<html>\n<p>\nThe (time varying) Integer output signal of this block can be defined in its\nparameter menu via variable <strong>y</strong>. The purpose is to support the\neasy definition of Integer expressions in a block diagram. For example,\nin the y-menu the definition \"if time < 1 then 0 else 1\" can be given in order\nto define that the output signal is one, if time ≥ 1 and otherwise\nit is zero. Note, that \"time\" is a built-in variable that is always\naccessible and represents the \"model time\" and that\nvariable <strong>y</strong> is both a variable and a connector.\n</p>\n</html>"));
