High-level, Natural, Transparent REXX Client Interface

REXX/CICS supports a high-level easy to use interface from client REXX execs to application servers through the ADDRESS keyword instruction in REXX. The ADDRESS instruction includes an external environment name that is used to determine the name of the external procedure that is called to process subsequent REXX command strings.

REXX/CICS provides the optional ability for the environment name (specified in the ADDRESS instruction) to be the name of an application server. This capability is provided by the REXX/CICS DEFCMD and DEFSCMD commands.

The DEFCMD command provides the ability to define (or redefine) REXX commands and environments, and it provides the ability to specify whether an environment-command combination is to be handled by a traditional CALLed routine or by an REXX application server.
