Available interfaces

CICSPlex® SM provides two interfaces for API users.

Command-level interface

This interface uses the CICS® translator to accept EXEC CPSM statements and translate them into the appropriate sequence of instructions in the source language. These instructions are then linked to an interface stub routine that is supplied by CICSPlex SM.

The command-level interface is available for programs written in the following languages:

Assembler Version 2 and later
OS PL/I Optimizing Compiler Version 2.3 and later
COBOL Compiler Version 1.3.2 and later
C Version 2.1. and later

Table 1 shows which languages are supported by the command-level interface in each environment.

Table 1. Programming languages supported by the command-level interface
Environment	Assembler	COBOL	PL/I	C
CICS TS	Yes	Yes	Yes	Yes
MVS Batch	Yes	Yes	Yes	Yes
MVS TSO	Yes	Yes	Yes	Yes
MVS NetView	Yes		Yes	Yes

Runtime interface

The runtime interface supports programs written as REXX EXECs in the following MVS environments:

Batch
TSO
NetView.

This interface consists of a REXX function package that is supplied by CICSPlex SM. The function package accepts commands in the form of text strings and generates the appropriate API calls.
