The Common Output Area (COA) on the terminal screen is the remaining top area of the terminal screen not used for the User Command Area or Task Status Area. It is a viewport on the log file. Hermes treats the log file as a ``book'' with numbered pages. ... The COA has two modes of operation: page mode and non-page mode. ... The current page number is displayed at the extreme right of the Task Status Area. ... When in non-page mode, Hermes can also scroll the COA instead of flipping pages. ...
