- The idea of shared code segments is fairly standard in minicomputer operating
- systems like VMS. Their solution should work well in the Mac case as well. In
- those cases the Library file is used as the reference point and the means of
- sharing code. In this case the library would hold the code segments and be a
- shared resource file to the applications. The segment numbers would be the
- same because all the applications would have been linked to the same library.
- A version number is usually used to ensure that the application's expected
- library matches the one found at run time.
-
- The main change would be in the linker to allow generating shared library
- output rather than always linking an application, and then again in resolving
- references to the library, and adding the library search and open to the init
- code generated.
-
- By making this a general feature of the operating system, not just a MacApp
- special case all comercial libraries could be distributed in this way such as
- the Sybase interface, Inside Out, and others.
-
- Now that the Mac operating system is competing with OS/2 and workstation
- operating systems, and the applications are getting sufficiently sophisticated
- to require comercial libraries to handle the scope of the work, I for one would
- like to see this feature come to pass.
