This is a simulation of helicopter rescue of the crewmen from stricken ships heading for the rocks.

The player has to rescue the three crewmen of a ship which is moving back and forth, approaching rocks, and land them safely on a cliff. If he hits anything or the ship reaches the rocks before all the crew have been rescued then he loses a life. If the player sue-ceeds then a new ship appears slightly nearer the rocks. To complicate matters further, there is a lighthouse and the ships and crew can only be seen when the light is on.

The program is not readily transportable as it uses a number of CPC464 specific features such as windows and interrupts called from BASIC. It includes a title and instructions within the program. It also has a high score record and new game option. ...

The program is full of REM statements to make it self-explanatory.

One special feature used deserves a mention. CPC-464 strings can include control characters. By including control characters in a string to move the cursor it is possible – for instance – to print a 2 x 2 block of characters (the helicopter) as a single string. If these strings were to be printed near the righthand edge of the screen then it is a feature of the CPC-464 that they would be moved to the next line. The CPC-464 looks at the length of a string and decides whether it will fit, ignoring the fact that it may contain control codes! The formatted print command – print using – free formats the printing so the printing stays where it is wanted.

Amstrad BASIC contains no method of checking the character at a given square so an array is filled to silumate the screen obstacles to the helicopter.

L'Amstrad CPC est une machine 8 bits à base d'un Z80 à 4MHz. Le premier de la gamme fut le CPC 464 en 1984, équipé d'un lecteur de cassettes intégré il se plaçait en concurrent  du Commodore C64 beaucoup plus compliqué à utiliser et plus cher. Ce fut un réel succès et sorti cette même années le CPC 664 équipé d'un lecteur de disquettes trois pouces intégré. Sa vie fut de courte durée puisqu'en 1985 il fut remplacé par le CPC 6128 qui était plus compact, plus soigné et surtout qui avait 128Ko de RAM au lieu de 64Ko.
