BLINK.BAS - Can't make it work!!!! Please help!!

I just got all set up with my programmer (it's a couple years old, but still seems to be functioning fine, it's the EPIC pro.) And I just bought the PICBASIC compiler. I loaded the sample program BLINK.BAS:

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

Low 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


BLINK.HEX: incase this means anything to you...

Using a 16F84A
I have MicroCode Studio set to 16F84A as well as meLabs Programmer v4.23
I am attempting to use the internal oscillator so have set meLabs to RC.
Watchdog timer: enabled
Power up timer: disabled
Code Protect: off

I am getting a "Code Programming Error at 0000" when I try to program.

I first erase the chip, and then read it and it reads:
0000- 3fff 3fff 3fff 3fff 3fff 3fff 3fff 3fff
0008- 3fff 3fff 3fff 3fff 3fff 3fff 3fff 3fff
0010- 3fff 3fff 3fff 3fff 3fff 3fff 3fff 3fff
0018- 3fff 3fff 3fff 3fff 3fff 3fff 3fff 3fff
etc...

I program the chip, it gives me the error, and it then I read it and it reads:
0000- 1e03 3fff 3fff 3fff 3fff 3fff 3fff 3fff
0008- 3fff 3fff 3fff 3fff 3fff 3fff 3fff 3fff
0010- 3fff 3fff 3fff 3fff 3fff 3fff 3fff 3fff
0018- 3fff 3fff 3fff 3fff 3fff 3fff 3fff 3fff
etc...

I've tried this with a half a dozen chips with the same result each time. Note that the chips have been on my shelf for a couple years too. In their anti-static packaging in a fairly dry, temperate atmosphere.

I notice that when I load the HEX file into meLabs, it automatically calls up a XT oscillator, and I have been changing it from XT to RC. Do I need to specify RC in MicroCode IDE or in the program somewhere?

Is there anything else I'm missing? Any help would be greatly appreciated, as I'm pretty new to this.

Well, first off ... The 16F84A doesn't have an Internal Oscillator.
RC mode is for an external Resistor and Capacitor.
But that doesn't explain your problem programming them.

Are you programming it in a Zif socket?
Or is the chip "In Circuit"?

If In-circuit, what else is connected to RB6, RB7 and MCLR?

huh.. good to know about the oscillator.. I'll have to look into that.
I am not using a zif socket, but it is not in-circuit either, I am just using the 18-pin socket on the EPIC programmer. I think my ZIF is not working for some reason. The chip reads all 0000's when I try to use the ZIF.

In the same folder as EPICWIN.EXE

There's a file named EPIC.HTM. Open it with a web browser.
Look at the section labeled EPIC Troubleshooting

One of them usually fixes most problems.
