Another way to do this:

PARAMETER cTextString
* width of edit control - width of scroll bars
nMaxWidth = _screen.ActiveForm.edit1.width -25

* Average characters for control
nLineLength = nMaxWidth / fontmetric(6)

cOutPut = ''
DO WHILE LEN(cTextString) > nLineLength

*determine the maximum number of characters that will fit on a line
cTmpString = LEFT(cTextString, nLineLength)

* find the last full word
nBreakPos = RAT(' ', cTmpString)

* bite off the chunk of text
cTmpString = LEFT(cTmpString, nBreakPos)

* add to output string
cOutput = cOutPut + cTmpString + CHR(13)+CHR(10)

* truncate the original string and repeat
cTextString = SUBST(cTextString, nBreakPos+1)
ENDDO

* use up what's left
cOutput = cOutPut + cTextString + CHR(13)+CHR(10)

* assign to control
_screen.ActiveForm.edit1.value = cOutPut

This is a rough. Some additional code may be is required.

A point of curiosity
With an Arial font, 10 pitch I get
txtwidth('ABCDEFGHIJKLMNOPQRSTUVWZYZ0123456789')/26 = 1.891
txtwidth('abcdefghijklmnopqrstuvwxyz01234567890')/26 = 1.4423
But fontmetric(6) = 6

Why?

>To determine the number of rows required to display a word wrapped text string in a form of a given width, I'm going to use the GetWordNum() function of VFP 7 and build each word wrapped line one at a time. I will keep adding words to a line until txtwidth() * fontmetric( 6 ) becomes greater than the form width at which point I will start building another line. Plus I'll add some logic for handling carriage returns and linefeeds.
