Help Pic16f628a

Hi everyone;

I'm trying to program a PIC16F628A with internal oscilator and no MCLR Resistor, however, it does not Work, and i don´t know what i'm doing wrong; can you help me ?

Here goes the code;

@ DEVICE pic16F628A, INTRC_OSC_NOCLKOUT
@ DEVICE pic16F628A, WDT_ON
@ DEVICE pic16F628A, PWRT_ON
@ DEVICE pic16F628A, MCLR_OFF
@ DEVICE pic16F628A, BOD_OFF
@ DEVICE pic16F628A, LVP_OFF
@ DEVICE pic16F628A, CPD_OFF
@ DEVICE pic16F628A, PROTECT_OFF


'76543210
TRISA = %00000000
TRISB = %00001110
CMCON = 7
VRCON = 0



Led1 VAR TRISB.6
Led2 VAR TRISB.5
Led3 VAR TRISB.4


Main:
HIGH Led1
PAUSE 2000
LOW Led1
HIGH Led2
PAUSE 2000
LOW Led2
HIGH Led3
PAUSE 2000
LOW Led3
Goto Main


END
