Sub Example_FieldLength()
	' This example creates an attribute definition in model space.
	' It then queries the initial value of the FieldLength property,
	' changes that value, and finally resets the value.

	Set attributeObj = ThisDrawing.ModelSpace.AddAttribute(height, mode, prompt, insertionPoint, tag, value)
