 FUNCTION FIELDTYPEX()

  Short:
  ------
  FIELDTYPEX() Returns type of field


  Returns:
  --------
  <cType> => field TYPE

  Syntax:
  -------
  FIELDTYPEX(expField)

  Description:
  ------------
  <expField> is either the numeric position of the
  field in the database, or the name of the field.

  Examples:
  ---------
   IF FIELDTYPEX(i) =="N"
     nSum += fieldget(i)
   ENDIF

  Notes:
  -------
  Just using VALTYPE(FIELDGET(n)) is fine, except that
  memo fields then show as type "C". Not always wanted.
