Then you will have to turn the memo into a fixed length field.

SELECT MAX(LEN(ALLTRIM(Field5))) AS MaxLength FROM .... INTO ARRAY aMaxLen
IF aMaxLen[1] < 255
   SELECT Field1, etc, SUBSTR(Field5,1,aMaxLen[1]) AS Field5...
ELSE
   *     
ENDIF
COPY TO () TYPE *

>I forgot to mention there are fields in the table field1, field2, field3, field4, field5. Field5 in a memo field and I need to pull that info out as well into the textfile.
