F54A: Make MR WACKER find the truant ERIC

The address of this interruptible subcommand routine is placed into bytes 0x09 and 0x0A of MR WACKER's buffer by the routine at 7D36 after ALBERT has spotted ERIC trying to escape and raised the alarm.
Input
H | 0xC8 (MR WACKER)
F54A | LD L,$1D | Set bit 7 of byte 0x1D of MR WACKER's buffer, making him run
F54C | SET 7,(HL)
F54E | LD L,$00 | Point HL at byte 0x00 of MR WACKER's buffer
F550 | BIT 0,(HL) | Is MR WACKER midstride?
F552 | JP NZ,$655E | Finish the stride if so
Now check whether a command list restart has been requested. This request will have been made if the lesson in which MR WACKER started chasing ERIC has ended, and the next lesson has just begun (see F74D).
F555 | LD L,$1D | Has a command list restart been requested (i.e. should MR WACKER end the chase now)?
F557 | BIT 0,(HL)
F559 | JP NZ,$7E8F | Jump if so
F55C | JP $6558 | Otherwise continue the hunt for ERIC
