I'm so confused

I have used Word for years, and believe I once knew how to do this,
but am getting myself more confused, the more I try and the more I
read.
I am using Word 2000.
What I need to do it format my whole document so that there is a page
break after every 22 lines of text and each line is 33 characters
long.
I have done the length of the lines, by setting my margin, but other
then going through and counting each line and putting in a page break,
I can't figure it out. Considering I have to keep going back and
revising the text, this is a pain, because every time I add a couple
of lines of text in the middle somewhere, then I have to count and
move all of the page breaks, because they are still in the first place
I put them.
Does that make sense?
I hope someone can point me to some help. I need this format for many
lengthy writings. I would like to have a template or know how to do it
easier.
Thanks,
Sandi
