Section 9. Programming
The second header line reports field names. This line consists of a set of
comma-delimited strings that identify the name of individual fields as given in
the datalogger program. If the field is an element of an array, the name will be
followed by a comma separated list of subscripts within parentheses that
identifies the array index. For example, a variable named values that is declared
as an array of four elements in the datalogger program will be represented by
four field names: values(1), values(2), values(3), and values(4). Scalar variables
will not have array subscripts. There will be one value on this line for each
scalar value that is defined by the table. Default fieldnames are a combination
of the variable names (or alias) from which data are derived and a three letter
suffix. The suffix is an abbreviation of the data process that output the data to
storage. For example, “Avg” is the abbreviation for average. If the default
fieldnames are not acceptable to the programmer, FieldNames () instruction can
be used to customized fieldnames.
The third header line identifies engineering units for that field of data. These
units are declared in the “Define Units” section of the CRBASIC program, as
shown in CRBASIC EXAMPLE. Definition and Use of a Data Table (p. 79).
Units are strictly for documentation.
Subsequent lines are observed data and associated record keeping. The first
field being a timestamp, the second the record (data line) number.

a list of default field names.
