moving the cursor

Having done this


set winid to open window for record newrec

I would like to position the cursor after the first paragraph of the window’s text.

When I try this


set insertion point to after last word of paragraph 1 of winid

or this


select after last word of paragraph 1 of winid

I get error messages.

Is there a way to move the cursor on the screen?

The standard text scripting of Cocoa applications does not support this, only some Carbon applications (like BBEdit or Tex-Edit Plus) seem to support this.
