Instruction manual

SECTION 3. REPORT: SPLIT
PC208W, Version 3.0, Instruction Manual 3-7
CAUTION: When using the Last Count
option, if the Start and Stop Conditions
(Sections 3.3.2, 3.3.3) are specified, they
must exist in the newly appended data or
SPLIT will never begin execution.
By selecting the Specific option and entering a
number, SPLIT will "seek" that position in the file.
This option saves time by starting part way
through a large data file. The number specifies
the number of characters into the file to seek
before processing data. A positive or negative
number can be entered. If the number is positive,
SPLIT will start reading from the beginning of a
file; if the number is negative, SPLIT will start
reading from the end of a file. All characters,
including spaces, carriage returns, and line feeds,
are counted. Beginning and ending points may
be specified.
Example 2
Example 3
In Example 2, SPLIT will skip the first 256
characters before it begins processing the data
in Input File. In Example 3, SPLIT will skip the
first 256 characters before beginning and stop
execution on character 1024.
In most instances, SPLIT automatically
recognizes the type of data file it is reading by
using Auto Select in the File Info field.
However, there are two exceptions:
• Reading Raw A/D Data from Burst
Measurements
To read this type of data and convert it to
ASCII, select Burst in the File Info box.
Once Burst is selected, the Number of
Values in Each Burst window in the Offset
Menu will become accessible. Enter the
number of elements in each Burst. This
number does not include the array ID
number or calibration data.
• Reading Data in Final Storage (Binary)
Format
If Start and Stop Offsets are used in parsing
the data, Final Storage (Binary) Format
must be selected in the File Info field. This
tells SPLIT that the file must be decoded as
Final Storage before counting the bytes. If
Offsets are not used, Auto Detect may be
chosen and the file will be processed
correctly.
This option works with all subsequent commands
except with the Transpose option (Section 3.3.1)
or the Select elements option (Section 3.3.5).
3.3.2 START CONDITION
A starting point may be specified to begin
processing data. If the Start Condition field is
left blank, SPLIT will start processing data at the
beginning of the data file. The starting point can
be any element within the array or a
combination of elements within an array.
For example, the data in Table 3.3-1 contains
seven elements per Output Array, representing
hourly data. Assume that this data file contains
one month of hourly data. To start processing
data at 1500 hours on the first day, the Start
Condition is expressed as 3[1500], where 3
means the third element within the array and
1500 is the value of that third element.
