CPI-C and LU 6.2
CPI-C applications can communicate with non-CPI-C LU 6.2
applications, such as APPC.
CPI-C does not support the following features that are included in some
LU 6.2 implementations:
• Sync Point/Back Out processing
• PIP data
• LOCKS=LONG
• MAP_NAME
• FMH_DATA
These must not be used in LU 6.2 applications if CPI-C is to
communicate with them.
