SECTION 4. SPLIT
4-12
when an interval count (n) is met, or when the
/F or F option is enabled and a STOP condition
is met. Results which are output at the end of a
file are referred to as Final Summaries and
those output at the end of a specified interval
are Interval Summaries.
The running total function (RunTotal) is different
from other Time Series Functions in that it
outputs a Final Summary and at every line that
meets the COPY conditions.
If no count is specified and neither the '/F' or 'F'
options are enabled, Final Summaries occur
after all arrays within the START and STOP
parameters have been read (e.g., the average
of all values). A Final Summary may also occur
when a count is specified for an Interval
Summary and the count is not evenly divisible
into the number of OUTPUT arrays present in
the input file. The Final Summary, in this case,
is calculated from an incomplete count interval.
The count in a Time Series Function is optional
and does not require a decimal point. To
determine the interval, SPLIT counts the
number of arrays which meet the specified
conditions (STOP, START, and COPY). If the
time sync function is enabled, the time series
functions remain synchronized to the starting
time even if a complete array is missing from
the input data. When elements are missing the
Time Series calculations are based on the
actual number of elements found.
Semicolons are used in Time Series functions
to separate the elements or expressions from
the count which determines the interval.
SmplMax and SmplMin require two elements
separated by a semicolon. The first is checked
for a max or min, while the second is sampled
on the max or min.
The following set of weather data from Mount
Logan Peak in Cache Valley, Utah gives a total
of seven elements each hour. This Field
Delineated OUTPUT, with title and column
headers, was generated by SPLIT. These data
are used in the following examples of Time
Series Functions.
