CICS® intercommunication takes place on SNA links, which assume that all system data is in EBCDIC format. To ensure that transmitted data is in EBCDIC format, CICS ASCII-based systems convert all fields except application data areas, which are converted by the receiving system. Table 2 shows where data conversion is done for function shipping and DPL between CICS systems. The table includes all the conversion done automatically by CICS systems.
