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 3 of the character's buffer is set (indicating that he is running), or if bit 6 of byte 3 (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 18 and 19 of the character's buffer, jump to it
2	If there is a continual subcommand routine address in bytes 27 and 28 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 14 and 15 of the character's buffer, jump to it
4	Restart the command list if bit 4 of byte 3 of the character's buffer is set (and carry on to step 5)
5	If there is a primary command routine address in bytes 8 and 9 of the character's buffer, jump to it
6	Remove any continual subcommand routine address from bytes 27 and 28 of the character's buffer
7	Collect the next primary command routine address from the command list, place it into bytes 8 and 9 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 18 and 19 of the character's buffer:

Address	Description
31670	Control the hook while it's flying
64005	Deal with a character who has been knocked over
64131	Deal with a character who has nearly recovered from being knocked over
64331	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 14 and 15 of the character's buffer:

Address	Description
25118	Control the sniper while active
31319	Make a gangster walk up or down until Sam arrives
62278	Control a character who is knocking on or opening a door (1)
62297	Control a character who has knocked on a door and is waiting for an answer
62339	Control a character who is knocking on or opening a door (3)
62892	Guide a character up or down staircases
62926	Guide a character across a floor to his destination
62971	Guide a character from one spot on the sidewalk or road to another
63209	Make a character walk up or down
63558	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 8 and 9 of the character's buffer:

Address	Description
24925	Reset a gangster's location and restart the command list
25081	Make the gangster at no. 15 lie in wait for Sam
25307	Control the sniper
25385	Make a gangster chase Sam
25420	Control a banknote
29354	Control a policeman (1)
29361	Control a policeman (2)
31338	Make a gangster walk up and down while watching for Sam
31594	Let Sam out of jail if necessary
59147	Do nothing
62976	Make a character go to a location
63198	Restart the command list
63281	Make a character drop Sam
63304	Make a character walk up and down until somebody knocks on a door
63423	Make a character open a door that has been knocked on
63520	Make a character walk up and down for a while
63530	Control a cat

We're dealing with one of the primary characters (222-229). Here we check whether there is a continual subcommand routine address in bytes 27 and 28 of the character's buffer. The answer is always no.

This entry point is used by the routine at 62080.

Bit 4 of byte 3 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 3 now.

Now we look for a primary command routine address.
