A simple program carrying out various vector operations in two‐ or three‐dimensional spaces is presented. The listings are given in A.S.A. FORTRAN IV. The program is of particular application in various forms of three‐dimensional and shell analysis as it can create and transform locally orthogonal co‐ordinates, etc. While these applications motivated its design, it is of very general use one such application is illustrated by applying the program to general perspective projection.
