Yes, the first 72 columns were for the program code, the 
last 8 were for the card sequence number.  But it was 
optional, and a lot of people didn't bother with it.  
Those who did, usually incremented the count by 10s so 
you could add stuff inbetween existing cards without 
needing to re-number (ie re-punch the whole deck!).
