Are there quotes around each field? If not, you can try something like (substitute your file name for test.sdf):

lnMaxRowWidth = 345
lnFields = ceiling(lnMaxRowWidth/254)
dimension arrFields[lnFields,4]
arrFields = 0
for ix=1 to lnFields
  arrFields[ix,1] = 'f'+ltrim(str(ix))
  arrFields[ix,2] = 'C'
  arrFields[ix,3] = iif(ix=lnFields,lnMaxRowWidth-(254*(ix-1)),254)
ENDFOR
create cursor junkpos from array arrFields
append from test.sdf type SDF
GO top
dimension myfields(1,4)
lnlength = 0
lilength = 0
lncount = 1
DIMENSION myfields(lncount,4)
myFields[lncount,1] = 'f'+ltrim(str(lncount))
myFields[lncount,2] = 'C'
myfields[lncount,3] = 10
myfields[lncount,4] = 0
for i = 1 TO LEN(junkpos.f1)+1
	lnlength = lnlength + 1
	IF ASC(SUBSTR(junkpos.f1,i,1))=44
		lncount = lncount + 1
		DIMENSION myfields(lncount,4)
		myFields[lncount,1] = 'f'+ltrim(str(lncount))
  		myFields[lncount,2] = 'C'
		myfields[lncount,3] = lnlength-1
		myfields[lncount,4] = 0
		IF lnlength > lilength
			lilength = lnlength
		ENDIF
		lnlength = 0
	ENDIF
ENDFOR
FOR i = 1 TO ALEN(myfields,1)
	IF myfields(i,3) < lilength
		myfields(i,3) = lilength
	ENDIF
ENDFOR
create cursor junkpos from array myFields
APPEND FROM test.sdf DELIMITED WITH "" WITH CHARACTER ','

I'm sure there is a better way. You can certainly improve this down and dirty code! :o)
