=head1 DESCRIPTION
|
|
|
|
Is used for callnumber computation.
|
|
|
|
User must supply a letter prefix (unspecified length) followed by an empty space followed by a "number".
|
|
"Number" is 4 character long, and is either a number sequence which is 01 padded.
|
|
If input does not conform with this format any processing is omitted.
|
|
|
|
Some examples of legal values that trigger auto allocation:
|
|
|
|
AAA 0 - returns first unused number AAA 0xxx starting with AAA 0001
|
|
BBB 12 - returns first unused number BBB 12xx starting with BBB 1201
|
|
CCC QW - returns first unused number CCC QWxx starting with CCC QW01
