Data conversion

Character data might sometimes have to be converted as it is passed between a client and CICS®. For example data conversion would be required if the data on the client is encoded in ASCII format but in EBCDIC format on CICS. Data conversion is performed by the CICS server.

Data conversion is controlled by ASCII and EBCDIC encoding schemes. Each encoding scheme is identified by a CCSID (Coded Character Set Identifier) that defines a set of graphic characters, and a CPGID (Code Page Global Identifier) that specifies the code points used to represent the graphic characters. For more information see IBM Character Data Representation Architecture Reference and Registry (SC09-2190).

Data managed by a CICS server can be accessed from client systems that use different ASCII encoding schemes. In this situation, each client system supplies a CCSID tag to CICS to ensure that the data is converted correctly.
