With any luck, AO-7 will outlive (or perhaps it already has) the IBM
punch card that caused the whole 5-digit thing in the first place.  Of
the constants in the universe, the first one is 42, immediately followed
by either 72 or 80, depending on your background.  We apparently had
programmers define the KEPs format, as both lines are 71 characters
long... :)

(For source code, columns 73-80 were reserved for sequence numbers, so
that when you dropped your deck, the cards could be reassembled in the
proper order.)
