In addition to the other posts, if you are running short of pins, take a
look at the LSxx164 family of serial in/ parallel out chips. You can
clock in the 7 segment pattern with two PIC pins, data and clock.
Visually, you won't see the bits go by. You don't really need the clr
pin, and can tie it to the bus. This will save 5 PIC pins, but add
another 14 pin chip.
