Today's game is the classic Lander (1979) adapted to the setting of Space: 1999. The objective of the game is to land the Eagle 1. This game uses ??differential calculus like the Cannonball game.

This is a simulation game. In a simulation game, the result should be as similar to reality as possible (constants and measurement units).

In this case, the most important thing is to define the gravity - the Moon's gravity is about 1/6 of Earth's gravity (the program wrongly indicates 9.8).

Another important thing in a simulation game is the unpredictability of the real world. In the current setting, the program ends up always having the same score values ??because the thrust is always the same and the thrust button is only available once in each cycle. It would be better if the propulsion had a little variation...

The random function is also important. When using the RND function you should initialize it with some information from the real world. For example: asking the user to "press a key to start" and after the user presses a key the program should call the RANDOMIZE function.

We invite readers to review the listings and make changes to the program. All Pascalated BASIC programs that we present in this series can be improved and all readers are invited to improve them.
