OCCURRENCE

   The occurrence class is an attribute of an occurrence that
   identifies the type of occurrence. The occurrence class indicates
   if the occurrence is a declaration, a reference, or one of the
   other classes in the list that follows. If the occurrence class is
   a declaration or reference, the occurrence class indicates what
   type of declaration or reference it is.

   The format for the occurrence class attribute is as follows:

   OCCURRENCE=(keyword[,keyword...])

   The occurrence class can be one of the following keywords:

   Declarations

   o  PRIMARY - most significant declaration

   o  ASSOCIATED - associated declaration

   o  DECLARATION - primary or associated

   References

   o  READ, FETCH - fetch of a symbol value

   o  WRITE, STORE - assignment of a symbol value

   o  ADDRESS, POINTER - reference to the location of a symbol

   o  CALL - call to a routine or macro

   o  COMMAND_LINE - command line file reference

   o  INCLUDE - source file include referenece

   o  PRECOMPILED - precompiled file include referenece

   o  OTHER - any other kind of reference (such as a macro expansion
      or use of a constant)

   o  REFERENCE - any of the preceding values

   o  BASE - Any base class of a C++ class

   o  FRIEND - Any friend of a C++ class

   o  MEMBER - Any member of a C++ class

   o  SPEPARATE - Any Ada package or sub-program unit defined
      as SEPARATE

   o  WITH - Any WITH of an Ada package or sub-program unit

   Other Occurrence Classes

   o  EXPLICIT - explicitly declared

   o  IMPLICIT - implicitly declared

   o  VISIBLE - occurrence appears in the source

   o  HIDDEN - occurrence does not appear in the source

   o  COMPILATION_UNIT - the declaration that contains all
      occurrences in a particular compilation unit

   o  LIMITED - Any Ada limited private type

   o  PRIVATE - Any private C++ objects, or Ada private type

   o  PROTECTED - Any protected c++ object

   o  PUBLIC - Any public C++ object

   o  VIRTUAL - Any virtual C++ object

   The previous keywords are SCA terms. For information on
   corresponding language-specific terms, request help for the
   appropriate language table (for example, FORTRAN_ATTRIBUTES_TABLE)
   under the Getting_Started help topic.

   An example using the occurrence class attribute follows:

     FIND OCCURRENCE=PRIMARY

   This query finds all PRIMARY occurrences of declarations.
