How can I get data from function?

Hello!

I am automating CorelDraw by using the Variant class, i.e.

in Delphi:
var
vCorelApp: Variant;
[...]
vCorelApp := CreateOleObject('CorelDraw.Automation.8');
vCorelApp.SetVisible(0);

or in C++Builder:
Variant vCorelApp;
[...]
vCorelApp = CreateOleObject("CorelDraw.Automation.8");
vCorelApp.OleFunction("SetVisible", 0);

and so on. Now I need to get data from Corel`s script function GetSize which has this declaration in Corel Help:

.GetSize .XSize = long*, .YSize = long*

i.e. GetSize returns datas by function arguments.

How can I receive XSize and YSize from GetSize function? Any code example will be appreciated.

TIA,
Elie
