No, these were new chips that I entered some simple code into and they froze. This is what I entered,

' Timer countdown test
trisa = 0
porta = 0
Start:
I var byte
for I = 1 to 2000
porta.0 = 1
pause 5000
goto Start

Why you say its locked?
That code posted don't do nothing, did the code compile without errors? Because its missing the "next" of the "for" command!

not only that but, where are you turning off the port bit?

[Picstar]

You are both right, made a error when I posted. HERE is what I entered:
the purpose of the whole program is to give me a visual indication of how long it takes to the chip to execute a loop and count down. I need this info for setting timing on portions of my programs. Hope this makes sense. P.S. my setup may not be correct but I'm an old geezer.

' Timer countdown test
trisa = 0
porta = 0
Start:
I var byte
for I = 1 to 2000
next I
porta.0 = 1
pause 5000
end

Update, I just realized that (I) should be a VAR WORD, since it will be over 255. Thanks for your input guys but the problem remains that I still cannot program these chips that talked about.

' Timer countdown test
trisa = 0
porta = 0
Start:
I var word
for I = 1 to 2000
next I
porta.0 = 1
pause 5000
end

Your posted code has several problems, beginning with the lack of capitalization for the register names.
Do you intend it to turn PORTA.0 to a one and nothing else? If so, why delay?

Your issue is likely with the configuration bits. Please post your code for configuration...

I have run to this many times. I used my Pickit2(tm) to erase the pic and then is was ok.

I posted the solution in your other thread have you tried it?
