A page consists of all the text between two page delimiters, including
 the trailing page delimiter.  The default page delimiter is the formfeed
 character. The three page entities are:

     PAGE  Specifies all of the current page.
     BPAGE Specifies all characters in the current page from the character
           preceding the cursor to the beginning of the page.
     EPAGE Specifies all characters in the current page from the cursor to
           (but not including) the page delimiter.

 You can change the page delimiter with the SET ENTITY command.
