Reducing the Size of the runtime

For a variety of reasons including limited system memory or concerns about runtime system overhead, it is sometimes necessary or desirable to reduce the size of the runtime by removing unused elements. This is accomplished by modifying the special file config85.c and relinking the runtime. Of course, any component removed from the runtime is no longer supported by the system. Programs that attempt to use those components may terminate in unexpected ways.

You can find the file config85.c in the lib subdirectory of your ACUCOBOL-GT installation.

config85.c supports the removal (or re-inclusion) of the following runtime components:

Comments in config85.c describe how to modify the file and indicate the approximate reduction in space that will result from the removal of each component.
