--------------------------------------------------------------------------
OLDRESULT VAR BYTE
FLAG VAR BIT
KEYPRESS VAR BYTE
RESULT VAR BYTE

TRISB=%11110000
PORTD=%11111111
RESULT =$FF
OLDRESULT=$FF


MAIN:
PORTD=OLDRESULT

GOSUB SCANKEYS

IF RESULT = OLDRESULT THEN MAIN
IF RESULT = 12 THEN MAIN

GOTO MAIN

SCANKEYS:
KEYPRESS=0

PORTB=%1000
GOSUB ROW
IF FLAG=1 THEN FIRSTCOLUMN

PORTB=%0100
GOSUB ROW
IF FLAG=1 THEN SECONDCOLUMN

PORTB=%0010
GOSUB ROW
IF FLAG=1 THEN THIRDCOLUMN

RESULT = 12
RETURN

FIRSTCOLUMN:
LOOKUP KEYPRESS,[1,4,7,10],RESULT
OLDRESULT = RESULT
RETURN

SECONDCOLUMN:
LOOKUP KEYPRESS,[2,5,8,0], RESULT
OLDRESULT = RESULT
RETURN

THIRDCOLUMN:
LOOKUP KEYPRESS,[3,6,9,11],RESULT
OLDRESULT=RESULT
RETURN

ROW:
FLAG=1

IF PORTB.4=1 THEN EXITROW
KEYPRESS = KEYPRESS+1

IF PORTB.5=1 THEN EXITROW
KEYPRESS=KEYPRESS+1

IF PORTB.6=1 THEN EXITROW
KEYPRESS=KEYPRESS+1

IF PORTB.7=1 THEN EXITROW
KEYPRESS=KEYPRESS+1

FLAG=0

EXITROW:
RETURN

END

but alot of errors appeared like this one:

error[105]d:\microc~1\keybad\keybad~1.asm 5: cannot open file (include file "c:\PBP245\16f877.inc"not found)

what is the problem??

Hi,
The problem is that the compiler can't find the file [/i]16F877.inc[/i] in the folder it's looking for it in. Make sure that file is in c:\pbp245\. Also you're saying that you're using a 16F877A but the compiler looks for the include file for 16F877. Make sure that you select the correct device in MicroCode Studio.
