If the documents you are working with are in Word or Wordperfect, you’ll need to create fields where the answers go. Usually by duplicating a field (cut/paste it into the different pages) and retaining the same field name is basically how you’d set it up. Once done, if you put a value the field once, it should repeat the value anywhere the field reappears. Once you’ve set this up you’ll probably have to save the document as a template, but I’m not familiar with the specifics in Word or WordPerfect. I’ve added some links I found for more details on working with fields in those applications. For Acrobat, it is detailed under the Help documentation.

Whatever the application you’re using, the common underlying idea is to make a field, give it a name or identity, and then repeat the field’s existence, keeping the same name/identity for each instance.

Best of luck.

or some other macro program?
