<p>
CSV Data Set Config is used to read lines from a file, and split them
into variables.
It is easier to use than the __CSVRead() and _StringFromFile()
functions.
+ It is well suited to handling large numbers of variables, and is also
useful for tesing with
+ "random" and unique values.
+ Generating unique random values at run-time is expensive in terms of
CPU and memory, so just create the data
+ in advance of the test. If necessary, the "random" data from the file
can be used in conjunction with
+ a run-time parameter to create different sets of values from each run -
e.g. using concatenation - which is
+ much cheaper than generating everything at run-time.
+ </p>
+ <p>
Versions of JMeter after 2.3.1 allow variables to be quoted; this
allows the value to contain a delimiter.
Previously it was necessary to choose a delimiter that was not used in
any values.
