PIC programming question

Hi all, I'm glad to join this forum and hope to get/give some usefull information here!

I have a question about a program, I've wrote for the PIC 16f84
I wantet some leds, connected to all the port B I/O ports to flash from both ends, to the middle and back again. I tried to solve it like this:

Start movlw b'10000001'
movwf PORTB
call DELAY
movlw b'01000010'
movwf PORTB
call DELAY
movlw b'00100100'
movwf PORTB
call DELAY
movlw b'00011000'
movwf PORTB
call DELAY
movlw b'00100100'
movwf PORTB
call DELAY
movlw b'01000010'
movwf PORTB
call DELAY
movlw b'10000001'
movwf PORTB
call DELAY
goto Start

But when I plug the PIC in the circuit, it only does

movlw b'10000001'
movwf PORTB
call DELAY
movlw b'01000010'
movwf PORTB
call DELAY
movlw b'00100100'

and then it starts over! What could the reason for this be?

Thanks for answering, all answers will be appreciated

Don't double post...

Like i said in the other post, disable the watchdog...
