Collecting Dynamic Call information on your application
  tells you:

  o  Your application's call tree structure

  o  What routines call other routines

  o  Which routines make the most calls

  Unlike the static call stree structure provided by
  SCA, the dynamic call tree produced by PCA shows the
  runtime characteristics of the relationships among your
  application's routines during a given test run.

  To collect Dynamic Call 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 Dynamic Call Information query category.

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

  o  Click on Collect in the Collector main window.

  For information on displaying the results of the
  Dynamic Call Information 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.
