help plz i want to make a digital clock using 74hc164 and picbasic pro

please help i want to make a digital clock using picbasic pro and pic 16f84a and shift register ic 74hc164 4 digit lcd and i tested the instriction shiftout it works good but i dont know much about variables and this if my first test program it count from 0 to 9 please i need help how to use variables with shiftout and if there r any other ways thank you .


Include "modedefs.bas"

DEFINE SHIFT_PAUSEUS 1000


TRISB = 0
TRISA = 1
main:
porta.0 = 0

SHiftOUT portb.0,portb.1,LSBFIRST,[252\8]
pause 1000
SHiftOUT portb.0,portb.1,LSBFIRST,[96\8]
pause 1000
SHiftOUT portb.0,portb.1,LSBFIRST,[218\8]
pause 1000
SHiftOUT portb.0,portb.1,LSBFIRST,[242\8]
pause 1000
SHiftOUT portb.0,portb.1,LSBFIRST,[102\8]
pause 1000
SHiftOUT portb.0,portb.1,LSBFIRST,[182\8]

Variables are just places in memory set aside to store ones and zeros, that place gets an alias (NAME) chosen by you when you write the program. Here is a thread to a tachometer I wrote using shiftout to a 4 digit LED display. A lot of what you need to do was done here. Look the code over and read all the posts. http://www.picbasic.co.uk/forum/showthread.php?t=9037
