The following VBA example links frames of paragraph text and then unlinks the first frame from the second.
Sub Test()
Dim s As Shape
Dim s1 As Shape
Dim s2 As Shape
Dim t As Text
Dim d As Document
Set d = CreateDocument
Set s = d.ActiveLayer.CreateParagraphText(3, 5, 7, 9, "This is a test.")
Set s1 = d.ActiveLayer.CreateParagraphText(0, 0, 4, 4)
Set s2 = d.ActiveLayer.CreateParagraphText(8, 8, 10, 10)
Set t = s.Text
' Link the frames together
t.Frame.LinkTo s1
s1.Text.Frame.LinkTo s2
s1.Text.Frame.UnLink
End Sub
