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
redirected to Final Storage Area 1, the time is
output and the total is sampled.
If time is
