A number representing the current adjustment mode and type. ! 90: Can be saved and later given to the "ad" request to restore a previous mode. ! 91: .pp ! 92: \&.P Read-only. ! 93: 1 if the current page is being printed, ! 94: and zero otherwise. ! 95: .pp ! 96: \&.L Read-only. ! 97: Contains the current line-spacing parameter ("ls"). ! 98: .pp ! 99: \&c. General register access to the input line-number ! 100: in the current input file. ! 101: Contains the same value as the read-only ".c" register.
