Problem with ports help plz

[Mus.me]

I think you have a few errors in your code:

1. If you want to flash the LEDs on PORTB, you must make PORTB an output:

TRISB = 0

2. The first pattern of LEDS only has 7 bit, make it eight:

PORTB = %01111111

3. At the end, just befor the loop ' GOTO Main' you need another PAUSE 100 of the LEDS will change too fast to see.

So the Main bit of your code should look like:

DEFINE OSC 4
TRISB = 0
PORTB = 0

Main:
PORTB = %10101010
PAUSE 100
PORTB = %01010101
PAUSE 100
GOTO Main

END

THANK U FOR HELPING ME, IT WORKS GREAT I WAS WRITING SMALL LETTERS THATS WHY ,THIS MY CODE
FOR LED MATRIX 5X9 AND 4017 IC IT SHOWS ": A A "
DEFINE OSC 4
TRISB = 0
PORTB = 0
J VAR PORTB.5
Main:
PORTB.6 = 1
PORTB = %00100001 '
PAUSE 1
J =0
PORTB = %00111010 '
PAUSE 1
J = 0
PORTB = %00100001 ' LETTER A
PAUSE 1
J = 0
PORTB = %00111111 'SPACE
PAUSE 1
J = 0
PORTB = %00100001 '
PAUSE 1
J =0
PORTB = %00111010 '
PAUSE 1
J = 0
PORTB = %00100001 'LETTER A
PAUSE 1
J = 0
PORTB = %00111111 ' SPACE
PAUSE 1
J = 0
PORTB = %00110101 ' DOTS :
PAUSE 1

GOTO Main

END

JUST THINKING HOW I DO MY VARIABLES TO SCROLL TEXT AND SHOW MANY LETTERS ,THANK U BOTH AGAIN ,
