Collecting test coverage information on your
  application can tell you how effectively and completely
  your tests exercise the codepaths in your application.
  Test coverage information can tell you which lines of
  code were, or were not, covered.

  To collect test coverage information on your
  application:

  o  Compile and link your application with the PCA
     Collector

  o  Run your application. This causes the PCA Collector
     to take control of your application. PCA diplays the
     Collector main window on your screen.

  o  From the File pull-down menu, create a data file
     into which the Collector places performance data.

  o  Choose the Coverage query category.

  o  Click on the query related to the coverage
     information you are interested in.

  o  Click on Collect in the Collector main window.

  For information on displaying the results of the
  coverage queries, refer to:

  o  The hardcopy manual, Guide to DIGITAL Performance
     and Coverage Analyzer for OpenVMS Systems

  o  The online help for the PCA Analyzer.
