I haven't had any problems with memo fields for as log as I can remember. The only warning I have is that you shouldn't use it if the data changes frequently. Every time you add data to a memo field so that the size grows over the "next block size barrier" (in lack of a better description), VFP allocates a completely new area for the memo data while keeping the old intact, resulting in what's called memo field bloat.
