Cannot use Random method in Console Application in Delphi 7

Is it not possible to use Random method in Console Application in Delphi? It won't compile and shows the error:

'.' expected but '(' found

When I try to do the same thing in normal application (with windows), it works.

The whole code I'm trying to compile is here:

program random;

{$APPTYPE CONSOLE}

uses SysUtils;

var iRan:integer;

begin
  Randomize;
  iRan:=Random(10);
  writeln(iRan);
  readln;
end.
