The default keys generated by the key building service (NAMESET) are 5 bytes long and can contain the full range of binary values (X’00’ to X’FF’). If your database does not support such values in keys, then choose the 8 byte character keys instead. 8 byte character keys are turned on by setting

SSA-NAME3-OPTIONS #23

to

8

.

If for example you have person and company names stored in the one database column and they are distinguishable by a name ’type’ field, then you can build a search key by combining the name type field and the SSA-NAME3 key. This then allows use of a dedicated Algorithm for each name type.
