Pressumably, Visual FoxPro uses this default conversion for compatibility: the idea of varchar is that the expression is NOT filled out with blanks, up to the maximum field length. Memo has this property, too.

Well yes BUT, the varchar field does have a stated max field length. Why not just convert it to a character field of equal length? You would gain the padding spaces but at least it would be compatible with other older software that don't support memo fields. (GIS in this instance.)
