DBFNTX/1026  Data width error

     Explanation:  When building an index, the initial evaluation of the
     key expression (on a blank record) produced a character value of zero
     length.

     Action:  Make sure the key expression will produce a value of the
     same length for all records.  Do not use functions such as TRIM() in the
     key expression.  To restrict the length of the key values, use the
     LEFT() or PADR() functions.

     This error can also occur when creating an index on an invalid field
     type (e.g., trying to create an index on a MEMO FIELD).  The maximum key
     length is 250 bytes.
