Hi Larry,
Ah that's most likely a Form Feed. Are you using New Page After in a section or hard coding Char (12), which is ASCII for Form Feed, into a formula?
ASCII 12 is the code for Form Feed but if you type alt-12 into a text editor and you should get the same character.
Are you exporting to Plain Text or Paginated? Paginated shouldn't insert the FF character. It defaults to 60 lines per page.
Thanks,
Brian
