Input
H | Character number (215-229)
63520 | LD L,11 | Set the door identifier in byte 11 of the character's buffer to 168 (which corresponds to no door, meaning the character will not be on door duty)
63522 | LD (HL),168
63524 | INC L | Set the walkabout duration counter in byte 12 of the character's buffer to 255 (meaning the character will walk up and down for a finite period instead of indefinitely)
63525 | LD (HL),255
63527 | JP 63309 | Make the character begin walking up and down
