activated at exactly the same time as the results are being transferred from the
AT to the server. Depending on the speed and other parameters of your PC,
there may be a small time during the transfer when the result number
requested can be read as invalid. Including this test in the loop will trap out
this error.
Instead of using the GetVariantResult function itself to determine if new data is
available, the NewDataAvailable function can be used. This function is
recommended for use when more than one item of data is to be read after new
data is available. For example, the NewDataAvailable function can be read in
the do loop until it returns true, after which any other OLE function can be
called to gather their return values knowing that all the data will be valid. Using
the NewDataAvailable function also means that checking for 'INVALID
RESULT NUMBER' and 'NO RESULT' return values is no longer necessary.

If you have no requirement for real-time analysis, but are interested in post-test
analysis of test results, off-line data analysis should be adopted. An example
of this would be to view the results file created the previous day.
As described in section one of this chapter, the batch result file is stored in a
text based Comma Separated Variable format (CSV).
A spreadsheet is an ideal environment to analyze and manage your test data.
Almost all spreadsheet applications are able to import a CSV file.
Once imported test results may be graphed, calculated, edited and printed like
any other data. Using a package such as Microsoft Excel, macros may be
setup to sort and extract the appropriate result sections, calculate and compile
reports and finally produce a printout for records.
Refer to your own application handbook for details of importing and
manipulating data.
