To prevent modifications to a journal, right-click the blank area at the bottom of the journal and select Lock. Additional reports are not added to the journal (as described in the following section). JMP instead finds an open unlocked journal or creates a new journal when you select the Edit > Journal command again.

To unlock the journal, right-click the blank area at the bottom of the journal and deselect Lock.

Alternatively, place separate reports in separate layout windows by using the Layout command, as described in Save Using the Layout Command.
