I think that you can do this with a simple search and find. I don’t know what version of Word you are using, but you can open up multiple documents and when you bring up the search and replace, there should be a pick or menu drop down that gives options for different directions in the document to search, and the last on the list is “search all open documents”.
I do this for replacing job and date information in my headers, no macro, no anything, just search and replace. I open up about 60 documents at a time, do the search and replace on them. Done. Whole procedure takes about 3 minutes to do 120 files.
Now, this is not the same as looking for only 3 different things that I look for, but it will remember the last 6 searches and what you replaced them with - I think it remembers up to 6.
So, you could bring up a batch of 60 documents and do it that way, then next batch and the search and replace fields will let you search for the same things.
Then you have to start over looking for the next batch.
I would think it should not take more than about 30 minutes of really boring activity -grin!
On the other hand, what I did when I was updating my 1995 MF references to 2004 MF, every time I cross referenced back to another section, I had used the world “Section”. So, I would open the documents one at a time and search for “Section”. Then I would copy from a list from another document and paste the new number/title to replace the reference in the section.
That takes longer, but, is more linear, less boring (somewhat). But, you have a small number of sections you are looking for, only Division 1 sections, though a large number of sections you need to open. without the craving to write a macro for the elegance of simply having done so (more time to write it than to actually do it all manually), this later system might be the best.
Some things seem like a boring task, but to automate them takes even more time. boring manual tasks are sometimes faster than ‘elegant solutions’.
