A detailed description of each of the units comprising the interpreter provides the reader with a useful introduction to the LISP language. It offers a basic minimum system of LISP functions with which more complex functions can be constructed. The techniques employed for this application were based on the characteristics and capabilities of the PDP-15 system. The most important aspects of LISP are as follows: (1) It is a formal mathematical language based on the theory of recursive functions (2) It is geared to processing symbolic rather than numerical data (3) Programs written in LISP are themselves lists. LISP is a programming language designed for processing lists, and from this it gets its name (LIST-PROCESSING). The object of this work is to use the LISP language as an integral part of a PDP-15 computer system. LISP processor for a PDP-15 computer system. International Nuclear Information System (INIS) Design: .An LISP interpreter for a PDP-15 computer system Lesson 20: Creating Alignment Stationing and Offsets.Lesson 19: Defining and Editing Alignments.Lesson 18: Drawing Tangents, Curves, and Spirals.Importing Sections From Multiple Surfaces.Creating and Processing Sections from Multiple Surfaces.Importing Sections From Single Surfaces.Defining and Processing Sections from Single Surfaces.Adding Breakline Data from 2D Polylines.Adding Breakline Data from 3D Polylines.Lesson 12: Working with the Terrain Model Explorer.Lesson 11: Creating Tag Labels and Object Tables.Lesson 10: Creating Label Styles for Lines and Points.Lesson 9: Labeling Lines, Curves, Spirals, and Points.Lesson 8: Importing Points from an ASCII Text File.Lesson 7: Organizing Points by Description.Creating a Point Group Using the Raw Desc Matching Tab.Specifying Automatic Elevations and Descriptions.Inserting Points from the Point Database.Copying a Project and Re-associating the Current Drawing.Reviewing the Project Directory Structure.Select the contour label, select a point near the contour label, and then press ENTER twice. On the Terrain menu, click Contour Labels, and then click Delete Labels. Use the following steps to delete a contour label. The contour label maintains its relative position on the contour. Select a contour to display its grips, select the grip at the center of the contour label, and then slide the contour label along the contour.Ĭlick to fix the contour label in its new position. Use the following steps to reposition a contour label. The contour appears to be broken around the contour label box, but is actually still intact as a continuous contour line.Ĭlick here to see an illustration of the contours labeled at 2 m increments. The contours are labeled every 2 m with a rectangular box border around the elevation text. Select a point near the lower-left corner of the current view for the Start point, and then select a point near the upper-right corner for the End point. On the Terrain menu, click Contour Labels Group Interior to display the Contour Labels - Increments dialog box.Įnter 2 m for the Elevation Increment, clear the Add multiple interior labels along each contour check box, and then click OK.ĭrag a line across the contours to be labeled. Under Name, select 1, click Set Current, and then click OK. On the View menu, click Named Views to display the View dialog box. In this exercise, you will assign elevation labels to the contours based on the label style set in the Contour Style Manager dialog box.
