    Routine:    DVOUT   

    Purpose:    Real vector output routine.   

    Usage:      CALL DVOUT (LOUT, N, SX, IDIGIT, IFMT)   

    Arguments   
       N      - Length of array SX.  (Input)   
       SX     - Real array to be printed.  (Input)   
       IFMT   - Format to be used in printing array SX.  (Input)   
       IDIGIT - Print up to IABS(IDIGIT) decimal digits per number.  (In)   
                If IDIGIT .LT. 0, printing is done with 72 columns.   
                If IDIGIT .GT. 0, printing is done with 132 columns.
