It won't but I will know when I plug in my chip and see if it works. The
 assumption
is that programming PICs is like programming EPROMS, you can either program
them a little, read back, if it programmed give it one more jolt and move on to
 the
next location, or you can simply program it for a fixed amount of time that is
"guaranteed" to program a location. (In the EPROM world these are 'intelligent'
versus 'dumb' algorithms, and dumb ones are way to slow on big EPROMS, but
fine on 2732s and their ilk)

If it means that I can keep on using a JW part for development even though
I've screwed up the CP bit, that makes it worth it to me.
