Hi,
You should understand that if you work with ASM then you must use only valid commands and macros allowed with your compiler.
Now, there is no MOV B.(X),C command. it depends on compiler; I think it will be assembled into MOV B.0,C command and INC X will not have an effect then.
To your purposes I suggest you:

	SETB	P0.1	; set pin as input one
	MOV	A,#0x80	; hold place of the result
LOOP:	MOV	C,P0.1	; read bit
	RRC	A	; keep bit
	JNC	LOOP	; do 8 itterations
; here Accumulator contains 8 bits read from P0.1

Do not forget to use external pull-up resistor for
pin of the port 0.
Btw, I do not understand why do you ask about array? Anyway, an array may be done:

BYTE_ARRAY: DB 0x00,0x01,0x02
WORD_ARRAY: DW 0x0000,0x0001,0x0002

Good days!
