Lazarus Pascal beep command -


i'm running lazarus on windows. make program "beep". appears can in pascal using:

windows.beep(300,500);

but not in lazarus! there command can use?

update: 

sysutils.beep()

this works, i'd set frequency , duration of sound

afaik functionality worked ages. (dev pascal on ten years old).

what different lazarus not automatically add windows uses clause, delphi does.
