'16C84 and 16F84'

I asked a while back if a 16C84 programmer would program
16F84's

Having just converted from the former to the later I have discovered...

The 16F84s seem to be programmed fine, and work fine, with my (Parallax)
16C84 programmer.

If code protect is set off, they verify fine.
If code protect is set on, they fail verify (but work fine).

(Try saying that three times fast.)

Conclusion: "Code Protect" must have something to do with read-protecting the
code.

Gee, you think?  :-)

The 16C84s verify properly with code protect set.

Proper programming sequence requires verifying the code while
programming and before turning the code-protection on. Works
perfectly with 16F84 too.

Which one is cheaper?
Why is Flash better that regular EEPROM?
16F84 takes twice as time to program...
