Terminology

Throughout this book, when the term "CICS®" is used without specifying any particular product or version level, it can be taken as a generic term for all the CICS family products.

The following CICS products run on computers of the System/370, System/390®, or zSeries® family, and support communication with CICS products that run on other hardware platforms. (Not all of these products run on all of these computers--for example, CICS Transaction Server for z/OS® Version 2 does not run on System/370.)


In this book, the term System/390 is used to refer to any System/370, System/390, or zSeries computer on which one of the above products can run. The term non-System/390 refers to the hardware platforms used by other CICS products--for example, iSeries® (used by CICS/400), IBM-compatible personal computers (used by CICS Transaction Server for Windows), and RISC System/6000 (used by CICS on Open Systems).

In statements that apply to each of the CICS products that runs on a System/390 hardware platform, the generic term CICS on System/390 is used to represent all of them. One of these CICS products is referred to by name only if there is a difference in its interface to non-System/390 products as compared with the interface from other System/390 products. Subject to explicitly-stated exceptions, interpret all references to CICS as applying to your CICS on System/390 product.

CICS/400->CICS function shipping refers only to function shipping from CICS/400 to CICS.
