To display source code in another module:

  1.  Choose Browse Source from the File menu on the main window.  From
      the submenu, select All to list all modules, select Symbolic to
      list only those modules for which symbolic information is
      available.  The Browse Source dialog box appears, listing your
      executable image, which is highlighted, and all the shareable
      images linked with it (for example, DEBUG and LIBRTL).  If the name
      of an image is dimmed, no symbolic information is available for
      that image.

  2.  Double click on the name of your executable image.  The names of
      the modules in that image are displayed (indented) under the image
      name.

  3.  Click on the name of the module whose source code you want to
      display.  The Display Source button is now highlighted.

  4.  Click on Display Source.  The source view now displays that
      module's source code.
