>Why is it that all varchar fields become memo fields when issuing a COPY TO ... TYPE FOXPLUS command? and is there a way to avoid it?

Even older versions of Visual FoxPro don't have a "Varchar" type. What would you convert it to, without losing data? The only type that supports a variable length is a Memo or Memo(Binary).

If you are sure that the varchar has no more than a certain number of characters (up to 254), you can convert the field to Character type, and then do the COPY TO.

Update: I hadn't worked with Varchar before; I now see that like character, it has a limit of 254 characters. 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.
