Null-capable fields used by the INCCHAR parameter

 

The INCCHAR parameter allows null-capable character-field and null-capable DBCS-field names to be specified. However, any logical comparison with a null-field value tests as false, and the record is not copied.

The copy command performs no special processing if the you specify the *RCD special value as the field name. The command only compares buffer default values for actual null values.
