    *Game Notes*

    Imagine a snow-covered mountain-side in the Austrian Alps. Television viewers are waiting to see world-class skiers tackle a long, difficult slalom, speeding downhill through a series of flag-marked "gates".

    You are going to control one of the skiers, using the Z key to move left and the X key to move right.

    Your skier must stay on course and will be disqualified if they miss a "gate". The longer they survive, the narrower the gap between the flags becomes.

    You can make the game more difficult at the start by reducing the value of J in line 150.

    *Program Notes*

    Lines 100 - 140: Define the "skier" and "flag" characters, then set up text and background colours.

    Lines 150-180: Store initial values of the variables.

    Lines 190-200: Select a random position for the left-hand flag.

    Lines 210-220: Scroll the screen and print the skier.

    Line 230: Ensures that the right hand flag is on screen.

    Line 240: Checks that the skier is between the flags.

    Line 250-260: Print a new pair of flags.

    Lines 270-330: Move the skier if the Z or X keys are pressed.

    Lines 400-410: Print the score and stop the program.
