영문초록 : In this paper, a new user interface for Common Lisp is introduced that is user-friendly, efficient, portable, and extensible. It remedies inconveniences of standard Common Lisp user interface with the introduction of various mechanisms like history lookup, command aliasing, shell escapes, function space management, and agenda. All the components are highly integrated to enhance usefulness of the whole system. It also provides many safeguards against mistakes often made by novices. Original design can be customized easily by the users at any time during the session. Since the whole system is written in Common Lisp and system-dependent parts are effectively isolated into a single module, it is quite portable across systems that provide Common Lisp.
