The KRONOS system provides an environment for scheduling the submission of
batch jobs that is easier and more functional than the SUBMIT/AFTER command. A
detached process is created which wakes up every hour to check a data base for
jobs that should be run.  Jobs may be scheduled to run at a given time, on a
given day of the week, on a given day of the month, on a given week day of the
month, on a given day from the end of the month, every day, every hour, on a
given day of the year, on week days only, etc.  Jobs can be run based on the
value of system logicals and system service item codes.  A user-friendly
interface program is provided to maintain the data base.  A variety of useful
example jobs are provided to demonstrate the use of KRONOS; included are System
Management, Security, Accounting, and Performance Monitoring jobs.

Complete sources are included.  Documentation on magnetic media.

Changes since last release: 
Cluster failover added, improvements in wakeup interval behavior, "runnable
list" command fixed, sample jobs improved and expanded, improved holiday
handling behavior, made more robust
