Bug? or my error?

[ttw]

I typed wrong. They are both the same CC. It's an intermittent error which makes it hard for me to track.

As every variable (except the argument to the routine) is LOCAL and each variable is initialized each time, I'm having trouble figuring things out. I'm not impressed with the PRIME; it's fast but so far useless. (And when I tried to update through the USB, my computer got fried so I cannot trust plugging it into another computer, too expensive.)

I also have trouble with other similar programs which create lists using "append" or "concat" and I get errors calling "nextprime" or "isPrime?" (I think that's the spelling.) All these error are intermittent. I may try just doing a hard reset even at the cost of having to re-type in all my programs.
