=head1 DESCRIPTION
|
|
|
|
Is used for callnumber computation.
|
|
|
|
If the user send an empty string, we return a simple incremented callnumber.
|
|
If a prefix is submited, we look for the highest callnumber with this prefix, and return it incremented.
|
|
In this case, a callnumber has this form : "PREFIX 0009678570".
|
|
- PREFIX is an upercase word
|
|
- a space separator
|
|
- 10 digits, with leading 0s if needed
