The Hobbit (v1.0): Routine at 7E5F

7E5F: Parser: IN or INTO

IN and INTO are usually prepositions, and are handled as such (7E6C, with class $70). The exception is when a verb may start here and the previous word was AND or a comma, in which case they begin a new command such as 'and in': the parser jumps back to 7DFB to treat them like a direction.
7E5F	BIT 1,E	May a verb start here?
7E61	JR Z,$7E6A	No: treat IN/INTO as an ordinary preposition
7E63	LD A,($B5CF)	A verb could start here - was the word just before this one AND or a comma?
7E66	CP $A0
7E68	JR Z,$7DFB	If so, IN/INTO really begins a new command (like a direction): treat it as one
7E6A	LD D,$70	Otherwise it is an ordinary preposition after all
