At the present time, CAESAR II doesn't know multiple users are working on the same job. When a user starts the piping preprocessor (the input module), the existing job file is read in and closed. All work is done on a <em>memory image</em> of the job file. When the users saves the data, the job file is opened and the memory image written into it.

We will have to re-visit this mechanism, and possibly change the program's operation to accomplish this <em>notification</em> ability.
