This is probably a very stupid question but I'll ask it anyway. I have a couple of each of these 7-Segment Displays:

I can make them display numbers fine but how in the $%$%^$%&^ do I make them display DIFFERENT numbers? I can make it display 44 or 4444 all day long but if I want it to display 12 or 1234 how would I wire the hardware? I'm going off the interface manual and using either the 4026 or 4511 with a 14M or an 08M (don't have a 20M or I'd go direct) I must be missing something? Any nudge in the right direction?
These are common cathode by the way...
Thank you!
