Everyone's A Wally: Routine at EABF

EABF: Process logic for the current room

Used by the routine at 8184.
EABF	LD A,(IY+$0F)	Get the current character's room.
EAC2	LD ($B951),A	Set this as the current room number. (B951)
EAC5	LD HL,$E80F	Point HL at the first action table. (E80F)
EAC8	CALL $AC6C	Get the pointer to the action table.
This entry point is used by the routines at EAE3, EAEB, EB95, EBC4, EBE2, EBED, EBFE, EC2B, EC34 and EDB3. At this point, HL points to the logic table of the current room.
EACB	LD A,(HL)	Put the next pattern in A.
EACC	INC HL	Move to the next position in the table.
EACD	CP $FF	Is this the end of the logic?
EACF	RET Z	Return if so.
EAD0	CP $F7	Is this an action?
EAD2	JR Z,$EAEB	Process it if it is.
If this isn't an action, it's a pattern, so look it up.
EAD4	ADD A,A	Double the pattern ID to get a word offset.
EAD5	LD E,A	Put this in DE.
EAD6	LD D,$00	Put this in DE.
EAD8	PUSH HL	Remember HL.
EAD9	LD HL,$E7E9	Add the base pointer for the match table. (E7E9)
EADC	ADD HL,DE	Add the base pointer for the match table. (E7E9)
EADD	LD E,(HL)	Put the address found in DE.
EADE	INC HL
EADF	LD D,(HL)
EAE0	POP HL	Restore HL.
EAE1	PUSH DE	Jump to the address pointed to by DE.
EAE2	RET	Jump to the address pointed to by DE.
