' D     - Start direction image for player.
' A     - The number of items you have collected.
' F     - The platform colour which you collide with.
' N     - The current height of Henry when jumping.
' SC    - Your current score.
' EXSC  - Increases with your score but gets set to 0 if it equals 2000 when 
'         you get an extra life. 
' LEVEL - The level number which effects the images of the doors.
' LIVES - Number of lives Henry has. 
' BONUS - BONUS=1 when you're in the normal level or BONUS=0 when you enter
'         the bonus stage. 
' BLINK - Time taken for player to start blinking if left alone. 
' TIME  - The level time limit.
' COUNT - Used to slow down the time.
' GONG  - Timer for the Gong sfx.
' BS    - Holds the Bonus screen number. 
' BUB   - Used to offset the bubble when Henry turns left and right. 
' BI to BIH - Turns an item(in the bath) on or off depending on if they've
