OpenGL display lists aren’t editable, so you can’t modify the call sequence in them or even see which calls are embedded in them. One way of creating a pseudo-editable display list is to create a hierarchical display list. (i.e., create a display list parent that contains calls to glCallList()). Then you can edit the display list by replacing the child display lists that the parent list references.
