The Solar System
As the title suggests this program deals only with our own Solar System, which it defines on the first page to 'include all objects captured by the gravity of our Sun.' TA first page of the program presents a menu listing the first eleven options which are allocated to the Sun and the planets.
Select any of those options and you will be given one or two pages on that topic. The information is very compressed and it is best described as a beginners' basic guide, at which level the information is interesting. The text is combined with diagrams that, in the case of the Sun show its structure, or for the planets their position and size in relation to the earth.
The information given with the planet text includes the diameter, orbit and rotation periods, moons and distance from the Sun. The other information that can be called up includes a diagram showing all of the planets in their relative positions, and basic information on asteroids and comets. This package does deal with the constellations, but only with ten of them and all it really does is to map them out in isolation to show the prime star in each case.
One final option is the seemingly obligatory quiz but really I feel that this program is nearer a pure educational package, so the quiz is essential.
The layout of the program is neat though unspectacular. The menu system was crude as the user has to enter a number and then press ENTER, a system that is at variance with that used by the other packages and is prone to errors, small point, perhaps, but in an educational environment these packages have to be idiot resistant.
