If you are in Word, go to "Edit", Replace or Ctrl H, then you will be presented with a dialogue to replace xxx with a space. I do not have the codes handy at this time. Hunt around. I will give it an honest try and get back to you. Do not despair.
I use Office 2000 and it all works the same. I found a setting in the top menu, click on Format then Paragraph and the second tap that says Line and Page Breaks. Play on this and good luck. I still have not found the code to go to "Replace" your Page Breaks with just a space. Anybody here ? The Page Break keystroke is wanted. OK, I found this : go to Help then Index then type "page break" then Search, the second option might help you. Bottom paragraph. Good...
