' NOTE:This source code can not be Run through the AMOS editor as some files 
' need to be copied into memory which is done in the startup-sequence of the 
' full Game(see Intro source code).
'
' The following source code reseaves the Main variables LIVES,SC,EXSC and
' LEVEL.It then asks you to 'Press Fire' on the loading screen and then starts 
' the Level. 
'
' Memory Banks Used: 
'  1 - Sprites - Sprites 
'  5 - Sound - Main samples
'  6 - Sound - In Game samples 
'  9 - Pac Pic - Control panel 
' 10 - Pac Pic - Background picture
' 11 - Pac Pic - Bonus screen background 
'
' Bobs and Sprites used: 
' Bob 1 - Fish 
' Bob 2 - Squirral 
' Bob 3 - Bird 
' Bob 5 - Bonus Entrance 
' Bob 10 - Henry Crying
' Bob 26 - Henry Hit 
' Sprite 8 - Player
' Sprite 10 - Snail
' Sprite 12 to 23 - Items
' Sprite 24 - Exit 
'
' Variables Used:
' X     - Player sprites x coordinates.
' Y     - Player sprites y coordinates.
' I     - Player sprite Image. 
' 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.
' SPLASH- Activates the drowning sequence. 
' CROW  - Timer for the Crow sfx.
