The Client Option is a programming environment that provides Open Client™ Client-Library routines you can use to build mainframe client applications.
The Client Option runs on an IBM z/Series or plug-compatible mainframe computer. It uses the LU 6.2 or TCP/IP communications protocols and is available for CICS.
The Client Option is also available for IMS TM and native
MVS. This document pertains to the Client Option for CICS only.
Client Option applications can communicate with two kinds of servers:
Adaptive Server® Enterprise (ASE) and Open Server™ on PCs and several mid-range UNIX platforms
Server Option applications running in a CICS region on the mainframe
Client Option applications can send requests to ASE and Server Option applications.
