Somehow I've gotten through a lot of C programming without an implicit understanding of high- and low-order bits. I know that I can check for a high-order bit using & 0x80, but how would I go about un-setting that? Also, if anyone has a good resource for delving deeper into this it would be appreciated.

Just AND it with all ones except for the bit you want off, which should be zero.
