Returns a random number within the rnage 0 <= X < Range. If Range is not specified, the result is a real-type number within the range 0 <= X < 1. See Randomize. Random involves "compiler magic" since it is not treated like a real function. The compiler creates code to call _RandInt or _RandExt, which can be found in the System.PAS unit. See efg's UseNet Post about this. See Ray Lischner's UseNet Post clarifying parameter. |

by David J. Taylor to work with Delphi 4's open array parameters, which
