| I think there may be a very slim chance that it is discussed in the cobol manuals. |

You could read an article "Static versus Dynamic Linkage in COBOL" written by the famous Jim Moore, an exceptionally gifted technical author.
You'll find this on my web site sites.google.com/site/schlabb/home/hints-tips/cobol
Generally spoken "static" means that the called program has to be present at link time and will be included into the calling program's load module by the linkage editor. "Dynamic" means that the linkage editor leaves all references to the called program unresolved. At run time this program will be loaded as a separate module.
There are advantages and disadvantages for both methods. Read Jim's article to dig deeper into these concepts.
From my experience most shops nowadays prefer dynamic linking. Each module can be maintained and activated separately without any need to re-link all calling programs. Several years ago performance has been the most important issue mainly for batch programs to choose static linking method. But I think you'll find these cases ever fewer.
Hope this helps |
