Brief history of cardnumbers and koha
Horowhenua Libraries get their cards with a barcode and a number on them.
The number conforms to the checkdigit routine.
So koha didnt need to generate cardnumbers. It just needed to check that the
number entered conformed to the checkdigit routine.

Probably make a little routine that generates numbers that fits that
checkdigit.
But what is more pertinent I guess is how to change the checkdigit routine
so it fits your existing numbering scheme.
At the momment the there is no easy way. Apart from hacking at the perl.

I dont know, ill leave this for someone more knowledgable to answer.

Nope, but i guess i could write something that would generate a list. As i
said the checkdigit routine should be abstracted out though i think.

There could be
