Sample CL Program to Retain System Date

--
Hi
I wrote this program to retain system date, I am
sending it to this forum because someone may need it
during the year end.
Schedule a job using ADDJOBSCDE command with schedule
time 00:00:01 calling this CL program. This program
will change
the system date back to the previous date.
