Larr; Rectangle 3. April 21, 2013. This is a variation of the program Rectangle 1. The difference is that it is the coordinates of the centre of the box which are input rather than the bottom left coordinates. The two programs are virtually identical except for the addition of lines 310 to 370 which simply convert the centre coordinates to the bottom left coordinates. Using the coordinates of the centre of a displayed shape is the conventional method of positioning a shape on the screen. 1 REM RECTANGLE 2.

This method would be employed if a machine code was being used to generate the display, but in Basic it is far easier to use one of the Basic commands provided. There are four graphics commands in Basic:. PLOT x, y this plots a single pixel at the specified x and y coordinates. You a...
