__CSVRead() example in attached zipped jmx (though don't yet know whether
it will be forwarded!)

Here's some notes on how to use __CSVRead(). The intention was to provide
LoadRunner-like parameterisation, so it should do the Job.

Hope it make's sense!!  If not I'll post an example

The CSVRead function returns data from a CSV formatted file. This is used
where parameter data must be varied for each iteration of the test plan.

A value is read by specifying the filename and position of the field within
a row as parameters to the function, eg:

${__CSVRead(c:/scripts/user.dat, 0) }                             (for a
Windows filename)

Note that variable positions in a row start at zero, and the value may be
read many times.


The next row in the file is accessed by issuing next() as the second
parameter:

${__CSVRead(c:/scripts/user.dat, next()) }

You need to create a dummy parameter in a sampler request in order to
execute next(), but this shouldn't be a problem for most applications - it
will just be ignored. It is also necessary to execute next() before reading
the first values from file. This means putting next() in a step that is
before the step where the first value is used.

Reading past the end of the file returns to the first record.

ALSO: The values returned are unique to each thread. So if you have many
threads, they will all see different data values.
