Basic Planetary Data
The
program PLANETS and PLANETDATA retrieve data about our solar system planets, including
our dwarf planet, Pluto.
PLANETS
presents you with a choose menu which will present a screen of all the data for
a planet.
PLANETDATA
allows you to retrieve a specific item for a planet. PLANETDATA has two arguments: n for the planet, k for the data point. This is useful if you want to pull out a
specific data point for calculations.

The
diameter of Saturn. PLANETDAT(6,2)
returns 58,232 km.
