Keypads HELP! hehe, Need advice and possible code.

I think you have a mistake here

INT_LIST  macro    ; IntSource,        Label,  Type, ResetFlag?
        INT_Handler   INT0_INT,  _KEYPRESS,   PBP,  yes
	endm
    INT_CREATE               ; Creates the interrupt processor
ENDASM
@   INT_ENABLE   INT0_INT     ; enable external (INT) interrupts

I belive it has to be like this ;

INT_LIST  macro    ; IntSource,        Label,  Type, ResetFlag?
        INT_Handler   INT_INT,  _KEYPRESS,   PBP,  yes
	endm
    INT_CREATE               ; Creates the interrupt processor
ENDASM
@   INT_ENABLE   INT_INT     ; enable external (INT) interrupts

actually both are same but you may wanna try

PS: also "X = PORTB <<4" statement is wrong, change it to "X = PORTB >> 4"
