Source listings and link-edit maps

Include the source listings of any applications written at your installation with your set of documentation. (They can often be the largest single element of documentation. Large installations with thousands of programs often keep such listings on microfiche.) Make sure you include the relevant output from the linkage editor with your source listings to avoid wasting time trying to find your way through a load module with an out-of-date link map. Be sure to include the JCL at the beginning of your listings, to show the libraries that were used and the load library the load module was placed in.
