You can bookmark a segment occurrence so that you can return to it later during the current editing session or during a later
               editing session. 
               		
               
Note: Bookmarks can be applied only to segment occurrences that have a unique concatenated key.

               When you create a bookmark, the IMS Database Editor stores the name, segment occurrence, and a description in a bookmark list.
                  Between editing sessions, the bookmark list is automatically stored in a bookmark file in the folder containing the database
                  you are editing. The bookmark file name has a 
                  		  
.bmf extension, and the prefix depends on the type of database:
