Line numbers are meaningless when using proportional fonts. How will you determine how many lines if the text uses different sized fonts?

>I'm using automation to create a word doc from VFP 8 (Word version = 2002).
>I open an existing document, then add text to it. What I'd like to do is determine the current line number of the current page in the Word document so I can include a page break, if necessary. My code looks like this:
>

>loWord = CREATEOBJECT("Word.application")
>WITH loWord
>  .Documents.Open("DocToOpen.doc")
>
>  WITH .ActiveDocument
>    *Grab a reference to the existing text.
>    loSelection = .ActiveWindow.Selection
>    WITH loSelection
>      	*Add Customer name and billing address.
>      	.InsertAfter(lcCustName + CHR(13))
>      	.InsertAfter(lcAddr1 + CHR(13))
>	IF !EMPTY(lcAddr2)
>	    .InsertAfter(lcAddr2 + CHR(13))
>	ENDIF
>	.InsertAfter(lcCityStZip + CHR(13) + CHR(13))
>
>	*Add salut, and default text
>       	.InsertAfter(lcSalut + "," + CHR(13))
>        .InsertAfter("Some introductory text goes here:" + CHR(13))
>      	*Then move down one line.
>      	.MoveDown(,1,)
>	*Scan the cursor and add items as necessary.
>	SELECT TestCursor
>	SCAN
>	    *Check where we are on the page...need a minimum of 4 lines.

>	    Endif
>	    .InsertAfter(FieldValue1 + CHR(13))
>	    .InsertAfter(FieldValue2 + CHR(13))
>	    .InsertAfter(FieldValue3 + CHR(13))
>	    .InsertAfter(FieldValue4 + CHR(13))

>I've tried a whole series of object and method combinations but haven't been able to locate the one for line numbers. Paragraphs, yes, but line numbers, no. I also realize there are other ways to do what I'm trying to do. I'm open to any suggestions, as long as they move me in the right direction. Thanks in advance.
