PIC programme doesnt run completely

[sse]

Hi all, help me please~ i met up some critical issued~
I'm using MicroCodeStudio as software and uic00b & icsp as hardware.
My question is ;
I'm 1st time bought an uic00b, did i need to setting up something in (PICkit 2)?
Following is my program BUT im not sure whether it's correct or not~
input/MCLR= 2 switchs
output=leds
4MHz as OSC, 30pF x2

CODE: SELECT_ALL_CODE

define OSC 4

trisa = %11111111     
porta = %11111111
     
adcon1 = 7             
flag var byte
flag = 0
trisb = %00000000       
portb = %00000000

START   

pb1:
if porta.2 = 0 then lampu1
goto lampu1

lampu1:
high portb.0
PAUSE 30
LOW portb.0
high portb.1
PAUSE 30
LOW portb.1
high portb.2
pause 30
low portb.2
goto lampu1
 
end


At the end, when the +5v supply is given to this circuit, the program r run automatically even i nvr press pb1(porta.2)~

Don know what are you writing, not familiar with basic.

So show us the schematic and better with the hardware photo.

why don't u try in C. Im sure there will be more people willing to help you if u write in C.
Cytron did a nice tutorial for beginner ... u can check it there..

Did you tie your porta.2 low? or you leave it hanging?

Apologise coz present with my poor languages but i'm still learning.
Here is my schematic:

But i modified the input pin to porta.5 yesterday

Did you tie your porta.2 low? or you leave it hanging?

Neither hanging or given low~

why don't u try in C. Im sure there will be more people willing to help you if u write in C.

u mean C language? ya, i'll try it next after i understood this 1st(coz some fren suggest that it's more simple than C)

low portb.2
goto lampu1

end

pb1:
if porta.2 = 0 then lampu1
goto lampu1

I think there's something wrong with the code above. Whether button at port a2 is pressed or not, it would go to "lampu1" and start blinking the LED.

I think you should change the "goto lampu1" to "goto pb1" for your program to work as intended.
