it looks like that you didn't even open the data book.

your port initialization is wrong you have to
change to bank 1, setup port then change to bank0
since you want to make B0  input then

    BSF    status,RP0            ; change to bank1
    movlw    B'0000010'        ; load I/O
    movwf    TRISB              ; do it
    BCF        status,RP0        ; change to bank0
