This report describes work in a continuing research effort on systems for computer aid to management. Specific applications to management problems include management-information systems, aids to conferencing and group interaction, and the ability to maintain highly flexible and dynamic records of various kinds and use them as a working framework. Special software developments for implementation and modification of interactive user aids include the Tree Meta compiler-compiler; the MOL940 machine-oriented programming language; four Special-Purpose Languages (SPL's), for high-level specification of user control functions; and a multipurpose interactive user-aid system (NLS) which integrates these components. Specially developed hardware coupled to the computer provides I/O service to six CRT user consoles. A novel display system uses small CRT's located in the computer room, with television coupling to the individual user consoles.
