The Archive System has been used by our company for over a
year and has been found to be a very clean and efficient system.  
There are no known bugs.

This system was written to run on an IAS3.1 Operating System
with SRD and SORT-11 utilities.  It is written in Fortran.

  DO NOT USE FORTRAN 77
  The Fortran 4 plus compiler should be used and not Fortran 77.
  As of the date this program is being submittd we just received
  our Fortran 77 compiler and this program dos not work on it
  properly.  We did not find out why yet.  The first obvious
  problem is that number of days since last archive is not 
  being calculated correctly under Fortran 77 which may indicate 
  other serious problems elsewhere not yet discovered.

The following files are given.  Detail documentation can be
found in the the Rno file.  Logic flowchart of Dayarc and its
routines also available if you write and request it.
