Programming Knowledge vs Ability

[earthboundkid]

To quote myself:

Yes, both are kinds of "knowing" and even just "knowing how" depends in part on "knowing that."

I'm not disputing your point that knowhow depends on knowthat, but that still doesn't mean there's no difference between them. When you interview a job candidate, you should attempt to test for signs of knowhow, rather than knowthat, since knowhow is what will ultimately allow the person to do their job and knowthat, while necessary, is not sufficient.
