C     THE SECNDS ROUTINE IS FIRST CALLED TO OBTAIN THE TIME
C     AS  THE  NUMBER  OF SECONDS SINCE MIDNIGHT.  THE FILE
C     NAME IS THEN CONSTRUCTED FROM THE NUMBER OF TENTHS OF
C     SECONDS  SINCE  MIDNIGHT  PLUS 100000.  THE OFFSET IS
C     ADDED TO FORCE THE NUMBER TO CONSIST OF 6  CHARACTERS
C     WHEN WRITTEN AS A DECIMAL INTEGER.  THE MAXIMUM VALUE
C     INCLUDING THIS OFFSET IS 963999.

C     STATED  AS  THE  NUMBER  OF  SECONDS  SINCE MIDNIGHT,
C     OFFSET BY THE VALUE  OF  ITS  SINGLE  ARGUMENT.   THE
C     DECSYSTEM-10  TIME ROUTINE RETURNS ITS FIRST ARGUMENT
C     IN THE FORM 'HH:MM' AND ITS SECOND  ARGUMENT  IN  THE
C     FORM  ' SS.T' WHERE HH, MM ,SS AND T FORM THE CURRENT
C     TIME STATED IN HOURS, MINUTES, SECONDS AND TENTHS  OF
C     SECONDS.   READ   STATEMENTS ARE USED TO CONVERT FROM
C     THE HOLLERITH FORM RETURNED BY THE  TIME  ROUTINE  TO
C     THE  NUMERIC  FORM  WHICH  IS  TO  BE RETURNED BY THE
C     SECNDS ROUTINE.  THE  CALLING  CONVENTIONS  FOR  THIS
C     ROUTINE  ARE THE SAME AS FOR THE VAX-11 SECNDS SYSTEM
C     SUBROUTINE WHICH  IS  DESCRIBED  IN  SECTION  C.6  OF
