First check whether the character is immobilised by a blown fuse.

Now to determine whether to move the character this time round. The answer will be yes if bit 7 of byte 0x03 of the character's buffer is set (indicating that he is running), or if bit 6 of byte 0x03 (which is flipped on each pass through this routine) is set.

The character will be moved. From this point, the following steps are taken:

Step	Action
1	If there is an uninterruptible subcommand routine address in bytes 0x12 and 0x13 of the character's buffer, jump to it
2	If there is a continual subcommand routine address in bytes 0x1B and 0x1C of the character's buffer - which there never is - call it (and then return to step 3)
3	If there is an interruptible subcommand routine address in bytes 0x0E and 0x0F of the character's buffer, jump to it
4	Restart the command list if bit 4 of byte 0x03 of the character's buffer is set (and carry on to step 5)
5	If there is a primary command routine address in bytes 0x08 and 0x09 of the character's buffer, jump to it
6	Remove any continual subcommand routine address from bytes 0x1B and 0x1C of the character's buffer
7	Collect the next primary command routine address from the command list, place it into bytes 0x08 and 0x09 of the character's buffer, and jump to it

The address of one of the following uninterruptible subcommand routines (or an entry point thereof) may be present in bytes 0x12 and 0x13 of the character's buffer:

Address	Description
7BB6	Control the hook while it's flying
FA05	Deal with a character who has been knocked over
FA83	Deal with a character who has nearly recovered from being knocked over
FB4B	Control a character who has stepped off the roof of a building

The address of one of the following interruptible subcommand routines (or an entry point thereof) may be present in bytes 0x0E and 0x0F of the character's buffer:

Address	Description
621E	Control the sniper while active
7A57	Make a gangster walk up or down until Sam arrives
F346	Control a character who is knocking on or opening a door (1)
F359	Control a character who has knocked on a door and is waiting for an answer
F383	Control a character who is knocking on or opening a door (3)
F5AC	Guide a character up or down staircases
F5CE	Guide a character across a floor to his destination
F5FB	Guide a character from one spot on the sidewalk or road to another
F6E9	Make a character walk up or down
F846	Make a cat run up or down

The address of one of the following primary command routines (or an entry point thereof) may be present in bytes 0x08 and 0x09 of the character's buffer:

Address	Description
615D	Reset a gangster's location and restart the command list
61F9	Make the gangster at no. 15 lie in wait for Sam
62DB	Control the sniper
6329	Make a gangster chase Sam
634C	Control a banknote
72AA	Control a policeman (1)
72B1	Control a policeman (2)
7A6A	Make a gangster walk up and down while watching for Sam
7B6A	Let Sam out of jail if necessary
E70B	Do nothing
F600	Make a character go to a location
F6DE	Restart the command list
F731	Make a character drop Sam
F748	Make a character walk up and down until somebody knocks on a door
F7BF	Make a character open a door that has been knocked on
F820	Make a character walk up and down for a while
F82A	Control a cat

We're dealing with one of the primary characters (0xDE-0xE5). Here we check whether there is a continual subcommand routine address in bytes 0x1B and 0x1C of the character's buffer. The answer is always no.

This entry point is used by the routine at F280.

Bit 4 of byte 0x03 of the character's buffer is never set, but if it were, it would mean that the character's command list should be restarted. Check bit 4 of byte 0x03 now.

Now we look for a primary command routine address.
