When you are dealing with a group of CMS files (or library members), some or all which you want to use as input to a comparison or search, you need to use the CMS file selection list.

In the case of a comparison, the CMS file selection list enables you to specify which files (or members) in the new group are to be compared with which files (or members) in the old group.

In the case of a search, the CMS file selection list enables you to specify which files (or members) in the group are to be searched.

To view the CMS file selection list for the files (or members) that you want to compare or search, you use the Selection List Menu.
