C   --*** USIDS *** (GEN3D) Read list of IDs
C   --   Written by Amy Gilkey - revised 05/21/86
C   --
C   --USIDS processes a list of IDs.  The ID list is checked for
C   --repetitions with the existing list and with itself.  Repetitions
C   --are flagged with an error message and ignored.
C   --
C   --Parameters:
C   --   IFLD - IN/OUT - the free-field index
C   --   INTYP - IN - the free-field type
C   --   CFIELD - IN - the free-field characters
C   --   IFIELD - IN - the free-field integers
C   --   LOLD1, LOLD2 - IN - the length of the existing IDs
C   --   IDOLD1, IDOLD2 - IN - the existing IDs
C   --   LENNEW - OUT - the length of the returned IDs
C   --   IDNEW - OUT - the returned IDs
C   --   * - return statement iff serious error
