Pagebreak in Richedit

How can I force a pagebreak in a richedit component? I want to write
blocks of text, each block being on a new page. I tried

richedit1.lines.add(#12)

and saving the output as an RTF file, but when I imported it into
word, the #12 had been translated into some sort of underscore and
there were no page breaks. I'm using D3.0 and W95.
