XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX   NOON XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
 
    Time Autostart with world time information for HP48G[X]  2nd Edition

Shows the world map and the noon meridian during day time in Asia, Europe and
America. Thus, it tells you where is noon time at present. NOON is independent
on local time, i.e., a person in America or elswhere sees in a given moment 
the same picture as somebody in Europe. To achieve this feature, NOON looks 
in its first run for a real on the stack, the deviation from Central European
Time (CET). For instance, if you are living in Eastern Standard Time (a 6-hour 
delay to CET) put a -6 onto the stack and run NOON. Then the original program 
reorganizes itself and from now on you see the correct noon meridian together 
with local time. A person living in central Europe must put 0 onto the stack. 
Time and datum are displayed at the screen's top in user-friendly fashion.

We propose to assign NOON to a key of your choice. Whatever is made, if a key
distinct from CANCEL is pressed while NOON is running, the calculator turns 
off. At the next switch-on NOON restarts automatically. Very convenient for 
having just a glance at date and time. CANCEL aborts program execution and 
the autostart feature. NOON is idle about 50% of its run-time, hence does'nt 
consume much power while watching the meridian in its slow move from East to 
West. Note that NOON does not use PICT, hence PPAR is not involved.
