CCSID reference information

Coded character set identifier (CCSID) is a 16-bit number that includes a specific set of encoding scheme identifiers, character set identifiers, code page identifiers, and other information that uniquely identifies the coded graphic-character representation.

Character Data Representation Architecture (CDRA) has the concept of a growing CCSID. This CCSID is one where the code page is not full and new characters are added over time as needed. To indicate a growing CCSID, CDRA uses a value of 65535 in the character set part of a CCSID. On IBM® i, a growing CCSID is indicated by a value of 32000 instead.
