Overflow text from one text box to another without splitting words

[SusanF2]

Creating a form. Page 3 has a text box, which when full needs the user to move into the text box on page 4. 

I don't want words to split .i.e

........."the text will end here but I w"

page 4 text box

"ant it to continue here"

I need the final "w" from the text box on page 3 to move onto page 4 with the rest of the letters "ant". 

Any help?

I don't see how this is possible. What if the last word/letter of field 3 is "a" and the next word on field 4 is "men". Is that one word ("amen") or two ("a men")? There are plenty of other examples. Just let the user enter it how they wish to.
