  The Compaq Source Code  Analyzer (SCA) is  an  interactive,  multilanguage,
  source  code  cross-reference  and  static  analysis  tool  that is
  designed to aid developers in  understanding  the  complexities  of
  large-scale software systems.

  SCA is included in the DECset Software Engineering Tools Package.
  SCA is integrated with the Compaq Language-Sensitive Editor
  (LSE). When SCA is used with LSE, you can interactively edit,
  compile, debug, navigate, and analyze source code during a single
  development session.
