Search and replace with variables

[Judy Bragg]

I'm wondering if there's a tool out there that will do a search and 
replace where the replacement is a variable rather than alternate text.  
I have a 1500 page manual where no variables were used. I'd like to 
implement them, but it's painful to think about doing it by manually.

Any ideas would be most welcome.
