This report presents a display oriented scheme to help the higher level language computer programmer to debug and analyze programs. Timed visual interpretive execution and a variety of user instituted functions permit an informative dialogue between the man and the computer. A prototype implementation of the system using FORTRAN as the higher level language is described, and the results are discussed from the point of view of the system developer as well as the point of view of the user. Also treated is the problem of what a time-sharing system should do to make graphical input tablets useful devices in a time-shared environment.
