YELLOW VAR PORTA.1
BUZZER VAR PORTA.3
OPTION_REG.7 = 0
DATA 0,..............??????? I don't know how to write this part!!!

SETPIN:
SETPIN:
i = 0 WHILE i<4 PIN = 0 GOSUB KEYPAD LET PIN = num i = i + 1
WEND

CHKAMD:
WRITE 1, PIN
PAUSE 200
READ 0, ADMIN
PAUSE 200

Using the link i provided and using MPASM to compile you need...

INCLUDE "KeyPad.bas"

DEFINE KEYPAD_ROW        4        ' 4 ROW keypad       
DEFINE KEYPAD_ROW_PORT   PORTB    ' ROW port = PORTB
DEFINE KEYPAD_ROW_BIT    3        ' ROW0 = PORTB.3
DEFINE KEYPAD_COL        3        ' 3 COL keypad
DEFINE KEYPAD_COL_PORT   PORTB    ' COL port = PORTB
DEFINE KEYPAD_COL_BIT    0        ' COL0 = PORTB.0

YourVar                  var byte

Start:
    @ READKEYPAD _YourVar
    ' plah plah
    '      plah plah
    '           plah plah
    '

and your keypad results will be stor in YourVar variable as follow

col0  col1  col2
  1     2     3   row0
  4     5     6   row1
  7     8     9   row2
 10    11    12   row3
