How to make sure that call numbers are sorted numerical?

• Article Type: General

Desired Outcome Goal:
How to make sure that call numbers are sorted numerical?

Procedure:
Numbers in call numbers are filled with leading zeros and therefore are sorted numerical and not decimal. This can be seen in the configuration.

Example

xxx01/tab/tab00.lng
H SGN ACC 42 00 00 Call number <- Filing-Routine 42

42 F suppress
42 F to_blank :/-,
42 F pack_spaces
42 F subfield_mab
42 F compress $!=+"#%&'()*;?[\]_{|}@
42 F expand_num <- In filing routine 42 numbers are filled with leading zeros
42 F char_conv FILING-KEY-04

This is how an index entry looks like:
01 z01_acc \
02 z01_rec_key \
03 acc_code ..............SGN
03 alpha .................L
03 filing_text ...........DA 0001973 <- here are the leading zeros
03 filing_sequence .......41549
02 z01_acc_sequence ........001141549
02 z01_hash ................168482291293
02 z01_aut_tag .............
02 z01_rec_key_4 \
03 aut_library ...........-CHK-
03 aut_doc_number ........000000000
02 z01_acc_sequence_see ....000000000
02 z01_number_of_doc .......00000
02 z01_cataloger \
03 cataloger_name ........BATCH
03 cataloger_level .......00
02 z01_open_date ...........20080724
02 z01_update_date .........20080724
02 z01_cataloger_library ...
02 z01_non_filing_char .....00
02 z01_update_doc ..........Y
02 z01_update_z0102 ........Y
02 z01_ref_type ............
02 z01_category ............ZZZ
02 z01_normalized_text .....$$dDA 1973 <-- normalized text is without leading zeros
02 z01_display_text ........$$dDA 1973
