Helicopter

Ever piloted a helicopter? No? Well neither have I, but here's your
chance. The game's aim is to land your helicopter on the landing
pad of a ship, without running out of fuel. You start with 500
gallons and this is represented by a green band. As the amount in
your tanks falls, the band becomes yellow, at 200 gallons, and red
at 100. If you leave the controls alone, your helicopter loses
ground and its height above sea-level decreases. Try the game for
yourself, using the keys 1 and 0. But don't forget that the
computer cannot sense if you are pressing two keys simultaneously,
so remember, one at a time! At first, you will probably sink a
number of times, but as you pick up the knack, you should aim to
use as little fuel as possible. Definitely, a challenging game!
Apart from the actual messages printed, all the other letters in
PRINT statements are graphic symbols. If you enter lines 1000 to
1060 first, then 10 to 30 and press RUN, the graphic symbols should
make more sense.
