    This is a perpetual calendar program for Zshell.  The month
and year are displyed on the first line of the screen.  To change
the month use right and left arrow keys.  (Right to increase
month left to decrease it.)  To change the year use the up and
down arrow keys.  To exit press the exit key.  The program will
return to the year and month where it as exited from last.
It will only work from years 1900-2155.  I hope you enjoy.
