High-level Client/Server Support

REXX/CICS provides integrated client/server support to REXX execs by providing facilities to allow REXX execs to act as clients (which make requests to REXX/CICS servers) and by providing facilities to allow REXX execs to act as servers (with the ability to wait for and process requests from REXX/CICS clients).

REXX/CICS facilities are provided which allow REXX/CICS servers to wait on requests from clients (WAITREQ), and to retrieve (C2S) and set (S2C) the contents of client REXX variables.

Note: Servers do not execute as nested execs of clients, but rather execute as parallel entities.

Servers use Automatic Server Initiation (ASI) to start automatically when they receive their first request.
