Overlay Programs

To enable the service layer to properly access the overlay program for your component, ensure that you do the following when writing your MIF file:

• Specify the name of the component instrumentation as part of the path definition for your component. For example:

     start paths
           name = "EXPOverlay"
           os2  = "names"
           unix = "/usr/lpp/sva/bin/names"
     end paths
  

  In this case, the value of the name statement is used in attribute definitions to refer back to this path definition. The operating system statement identifies the filename of an OS/2 dynamic link library (DLL) that functions as the overlay program.

• In the definition for any attribute that requires instrumentation to provide its value, specify the path definition. For example, in the attribute definition use the following statement:

      value = * "EXPOverlay"
  

  This identifies the previous path definition by its name statement and enables the service layer to load the proper overlay program to retrieve the attribute's value.
