Using CPI Communications

Note

After reading this chapter, refer to the Common Programming Interface Communications Reference for complete details on coding CPI Communications routines.

Also read Installing and Testing Transaction Programs for information about supplying TP profiles and side information on MVS.

Like the MVS-specific TP services, CPI Communications lets your programs communicate with other programs on the same z/OS system, other z/OS systems, or other operating systems in an SNA network. However, CPI Communications has the advantage of portability: programs using CPI Communications can be moved between different systems with minimum changes.
