'In this example, the variable "counter" is incremented by 1 each scan. The data table
'is called every scan, which includes the Sample(), Average(), and Totalize()
'instructions. TrigVar is true when counter = 2 or counter = 3. Data are stored when
'TrigVar is true. Data stored are the sample, average, and total of the variable
'counter, which is equal to 0, 1, 2, 3, or 4 when the data table is called.

7.8.10 NSEC Data Type
Data of NSEC data type reside only in final data storage. A datum of NSEC
consists of eight bytes — four bytes of seconds since 1990 and four bytes of
nanoseconds into the second. Nsec is declared in the Data Type parameter in final-
data storage output-processing instructions
(p. 454). It is used in the following
applications.
