Re: CICS for the AS/400

Ken, Here's the scoop from the V4R5 Handbook

IBM CICS Transaction Server for AS/400 V4R4, 5769-DFH
The CICS platform is widely-used as a basis for implementing business 
solutions. CICS for
AS/400 enables many of these existing applications to be made available on 
the AS/400
system without excessive costs of code conversion. AS/400 applications can 
coexist with
CICS applications.

CICS for AS/400 supports CICS COBOL Command-Level or C applications on the 
AS/400
system. It is based on a major subset of the CICS/ESA Application 
Programming Interface
(API) and supports Minimal Function Basic Mapping Support (BMS).
If a user wants to write an application program using the CICS for AS/400 
API, then ILE
COBOL for AS/400 (see "IBM Integrated Language Environment COBOL for 
AS/400 V4R4,
5769-CB1" on page 634) or ILE C for AS/400 (see "Integrated Language 
Environment C for
AS/400 V4R4, 5769-CX2" on page 638) is required. COBOL or C applications 
developed for
CICS/DOS/VS, CICS/OS/VS, CICS/ESA, CICS/MVS, CICS/VM, CICS OS/2, and 
CICS/6000
are generally source-compatible with CICS for AS/400 if they use only the 
CICS
command-level API. Application support is available for both single-byte 
and double-byte
character-set based applications.

Basic Mapping Support (BMS) maps are source-compatible, provided they use 
only CICS
family base level BMS when ported to CICS Transaction Server for AS/400. 
The CICS
macro-level API is not supported by CICS for AS/400.
CICS for AS/400 offers server support for direct communication with 
workstation-based CICS
clients over SNA APPC links, without the need for an intermediate CICS 
OS/2 server.
Improved data integrity is ensured with CICS for AS/400 exploiting the 
OS/400 two-phase
commit capability. When a CICS for AS/400 application updates multiple 
systems, it ensures
successful updates of all files and backs out partial updates if the full 
transaction is not
completed. CICS for AS/400 two-phase commit support provides a backward 
recovery
facility.

The Inter-Systems Communications (ISC) facilities of CICS for AS/400 
allows connectivity to
other CICS platforms, giving access to both applications and data on those 
systems. CICS
for AS/400 supports ISC functions on the following products:

? CICS for AS/400 (other AS/400 systems running CICS for AS/400)
? CICS/ESA V3R2 and V3R3
? CICS/MVS V2R1
? CICS/VSE V2R1
? CICS OS/2 V1R2 and V2R0
? CICS/6000 V1R1

CICS for AS/400 InterSystem Communications (ISC) capabilities allow OS/400 
users to
share data and applications with other CICS systems. Enhancements include 
a binary call
interface from other languages and more simplified OS/400-based 
administration.
V4R4 Enhancements

Formerly called CICS/400, this product not only has a new name, CICS 
Transaction Server
for AS/400, it also comes packaged with two other products. CICS Universal 
Clients, and
CICS Transaction Gateway are delivered with the CICS Transaction Server 
allowing you to
enable your e-business right away.

Is anyone using CISC/400?

We are migrating some CICS based applications from an IBM mainframe to the
AS/400 and these applications are currently running in a CICS environment.

The most current manual I can find is for V3R1... Is CICS even supported 
in
a V4R4+ environment?
