Declaring a variable.
// Create a rectangle shape
MyShape is diagRectangle
// Set the dimensions, position and background color
MyShape.X = 100
MyShape.Y = 100
MyShape.Width = 350
MyShape.Height = 150
MyShape.Background.Color = PastelRed
MyShape.Comment = "Rectangle"
// Reference the displayed diagram
MyDiagram is Diagram <- DIAGEDT_MyDiagram
// Add the rectangle shape to the diagram
Add(MyDiagram.Shape, MyShape)
// Display the comment of the shape
Trace(MyDiagram.Shape[1].Comment)
// Move all shapes down
MyDiagram is Diagram <- DIAGEDT_MyDiagram.Value
FOR i = 1 TO MyDiagram.Shape.Count
Shape is diagShape
Shape <- MyDiagram.Shape[i]
Shape.Y += 10
