Paul McJones and Nelson Beebe for these, as well as to all the original

GEV Inspector/Editor for Lisp Data GEV (for GLISP Edit Value) is a display-based program which displays Lisp data in a window according to its GLISP datatype description. The user can "zoom in" on data of interest, display computed properties of objects by menu selection, send messages to objects, and write looping programs interactively using menu selection. GEV is available for Interlisp-D and for Interlisp-10 using a Heath-19 terminal. A demonstration file for GEV is available. From Interlisp, enter LOAD(<GLISP>GEVLOAD.LSP); then try (GEV C 'CIRCLE) and (GEV HPP 'PROJECT). The commands which can be entered at the "GEV:" prompt are as follows: Q Quit. POP Pop up to the earlier GEV edit window. E Edit the current item using the Lisp editor. PR Write a looping program using menu selection. P Display a menu of computed PROPerties for selection. A Display a menu of ADJectives for selection. I Display a menu of ISA adjectives for selection. M Display a menu of Messages to the object for selection. R Redraw the current window. T n Print the data type of item n. n Push down to "zoom in" on data item n. When a menu option is selected, a separate menu is displayed and a "Menu:" prompt is given. Menu selections are made by entering the number of the desired menu item (followed by a carriage return). "Q" may be entered instead of a number to leave the menu mode without making any selection. The data used for the demonstration is contained in the file GEVDEMO.LSP. Documentation on GEV is contained in HPP Memo HPP-82-34, copies of which may be obtained in MJH 225. While designed for use with GLISP, GEV may be used for any Lisp data which is described by a GLISP structure description.
