Hello This is my first time in PIC's world.

I am using 16f84a with Melabs programmer.
I am trying to flash a led at PortB.0 and here is the code and
circuit diagram is at http://www.trendztechnologies.net/good.jpg

loop:
High PORTB.0 ' Turn on LED connected to PORTB.0
Pause 1000 ' Delay for .5 seconds

Low PORTB.0 ' Turn off LED connected to PORTB.0
Pause 1000 ' Delay for .5 seconds

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

At all the ports i have 0.74 reading.
LED is constant but it is not blinking.

Could you please suggest me what's wrong with this.
