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