Exiting from a loop exits the function instead

Question

I've been coding in Inno Setup this afternoon and I read some Pascal documentation which says that exit is used to exit a loop. I tried using that in my code and instead it exited the function. For example in this function the message box will never be shown:

function NextButtonClick(CurPageID: Integer): Boolean;
var i: Integer;
begin
    Result := True;

    for i := 0 to 4 do
    begin
        exit
    end;

    MsgBox('test',mbInformation,MB_OK);
end;

I did some more googling and Pascal also has the break keyword so I used that and it works properly. Is exit really supposed to be used to exit the function? I recall reading this afternoon that Pascal does not have the equivalent of a C style return statement.

I really need some good documentation for the version of Pascal that Inno Setup is using. I have read the Inno help pages but they don't cover things like this. Thanks

You are using the wrong documentation, your link refers to the Sun Workshop Compiler Pascal 4.2. Inno setup uses as scripting language The RemObjects Pascal Script Which is a Delphi-like Pascal dialect, the official documentation of the Pascal Sripting used by Inno is located here, additionally you can check the Marco Cantù's Essential Pascal.
