oK HERE IT IS:

loop: High PORTB.0 ' Turn on LED connected to PORTB.0
Pause 500 ' Delay for .5 seconds

Low PORTB.0 ' Turn off LED connected to PORTB.0
Pause 500 ' Delay for .5 seconds

Goto loop ' Go back to loop and blink LED forever
End


aslo, I tried this code I found on google and it works fine:

pragma target chip 16f628 -- no 16f818 support yet
pragma target fuses 0x3F22
pragma target clock 20_000_000
pragma target osc hs

include jpic
include jlib

var bit LED is pin_a0
pin_a0_direction = output

asm bsf status, 5
var volatile byte ADCON1 at 0x9F = 0x06 -- disable port a analog functions
asm bcf status, 5

forever loop
LED = low
delay_10ms( 25 )
LED = high
delay_10ms( 25 )
end loop
