SAS/C Software Overview

SAS/C CICS Command Language Translator

The SAS/C CICS Command Language Translator is another powerful tool that is included with the base SAS/C product. The CICS translator enables you to develop application programs under OS/390 or VM and target them to run under CICS. This application-programming interface enables you to request CICS services by placing CICS commands anywhere within your C or C++ source code. The SAS/C CICS translator translates these commands into appropriate function calls for communication with CICS. All CICS commands are supported, including Business Transaction Services, Distributed Program Link (DPL) commands, and Front End Programming Interface (FEPI) commands.

The following are some of the unique features offered by the SAS/C CICS run-time library:

CICS Transaction Server for OS/390 1.3 and all previous releases back to CICS/VS 1.7 are supported on OS/390. In addition, CICS/VSE Version 2.3 and all previous releases back to CICS/VSE 1.7 are supported on VSE systems.
Support for the CICS Systems Programming Environment allows CICS systems programs to be written in C.
All-resident support allows a module to be built containing all the transient library routines needed by the program.
I/O support for JES spool files enables you to retrieve a file from the JES spool, write a file directly to the JES spool, and send a file to a remote destination using standard C library I/O functions.
Dynamic loading support provides compatibility with OS/390 and CMS.
For applications programs link-edited as AMODE 31, the C stack and heap can be allocated above the 16Mb line.
Most of the SAS/C run-time library for CICS can reside above the 16Mb line.
