>>>I am trying to create a cursor by using an sql statement. One of my fields is a function. It sends four dates as parameters to the function. The function analizes the dates to find the lateest date. I need to return this value back to the cursor as a value for this field. Right now I get data mismatch. Please help.

Saw it and you're right. However, this does work

SELECT MaxDate(date1, date2, date3, date4) AS Latest;
  FROM TableAlias;
  ORDER BY 1;
  INTO CURSOR Foo

FUNCTION MaxDate

  LPARAMETERS date1, date2, date3, date4
  RETURN MAX(date1, date2, date3, date4)
ENDFUNC
