In the above example, all samples for the
average are stored in input locations. This is
necessary when an average must be output with
each new sample. In most cases, averages are
desired less frequently than sampling. For
example, it may be necessary to sample some
parameter every 5 seconds and output every
hour an average of the previous three hours
readings. If all samples were saved, this would
require 2160 input locations. The same value
can be obtained by computing an hourly
average and averaging the hourly averages for
the past three hours. To do this requires that
hourly averages be stored in input locations.
Instruction 80 is used to send the 1 hour
average to Input Storage and again to send the
3 hour average to Final Storage.

8.2 RAINFALL INTENSITY
In this example, the total rain for the last 15
minutes is output only if any rain has occurred.
The program makes use of the capability to
direct the output of Output Processing
Instructions to Input Storage.
Every 15 minutes, the total rain is sent to Input
Storage. If the total is not equal to 0, output is
