Initiating 18F452

I am initiating 18F452. I am used Microcode plus - pic beginner's all-purpose symbolic instruction code pro pbp2.46 and mpasm suite.

As to configure the configuration bits? What necessary to add to the code?

Code:

---

'INCLUDE "P18F452.INC"

define osc 20

TRISB = %01000000 'set PortB to output
PORTB = %00000000


loop
HIGH PORTB.1
pause 1000
low PORTB.1
pause 1000
goto loop

---

Help me please
