The Cross-Reference Query window lets you specify a cross-reference
  query.  A cross-reference query matches occurrences of a symbol you
  define by specifying one or several of the following selection
  attributes:

     o  Name-Specifies the name of a symbol. SCA selects
        occurrences with names that match the name
        expression you provide.

     o  Usage-Restricts occurrences based on the usage of
        the symbol you pick (for example, the declarations
        of a symbol).

     o  In File-Specifies the name of a file.  SCA selects
        occurrences whose source position is in the file
        you specify.

     o  Type-Restricts occurrences based on the type of
        symbol you pick (for example, arguments).

     o  Domain-Restricts occurrences based on the
        symbol domain.  The domain indicates the scope of a
        symbol's declaration.  SCA selects occurrences whose
        symbol domain is one of those that you select.

     o  In Module-Restricts occurrences to those
        occurrences contained in the module that you
        specify.

  For example, if you want to find occurrences based on
  a name, click in the name text entry field and type in
  the name.  If you want to find occurrences based on
  symbol usage, click in the symbol selection list on the
  selection(s) you want.

  You can base a query on as many attributes as you like.

  After entering the attributes, select one of the radio
  options below, indicating whether you want to create a
  new query, or somehow modify the results of the
  previous query.

  Finally, select either the OK or APPLY button to
  perform the query.
