Hi Jang,
Thank you very much for your prompt response!!! I tested the script on a sample book, so no worries. 
I am using FMv10. It crashed on me several times while running the script. Could you please post the updated code that uses doc.MainFlowInDoc.FirstTextFrameInFlow.FirstPgf;?
BTW, what is "linked list of paragraphs"? Interesting. It's the first time I encountered this concept.
Again, **Kudos** to you for crafting this script!
