Macropod,
Thanks a million. Works like a charm. My hat is off to you. It's an ingenious solution that totally eluded me. I thought the REPLACE had to be equal to some kind of FIELD code. Never imagined that a field code value could be grabbed from the clipboard and applied all over a document.

In short, this trick is a tremendous time saver in my situation because I don't only "Paragraph 5.4.3' to change but a bunch of other paragraph number references that repeat all over the manual. I estimate I have at least 1,000 paragraph references to setup. Sure beats using the Cross Reference Dialog box and doing them one by one.

Again, thanks a million. Cheers.
