GP4 reliable output

[skimask]

Hi all,
I need to use GP4 as an output on a 12F629. I know a pullup to Vcc works, but does anyone have a sure way to make it VERY reliable?
Thanks for the help!

What's not reliable about it? If the power is good, ground is good, clock is good, why shouldn't GP4 stay where it's supposed to?
If you're that worried about it, keep writing to the port in your program.
