viii CICS Supplied Transactions
Preface
What this book is about
This book tells you how to start the transactions supplied with CICS. It tells you how to
control the CICS system, how to send messages, how to collect statistics, and how to get
terminal error information. It is also useful if you are responsible for preparing procedures for
people who operate such terminals.
The book also describes how you can use the operating system console as a CICS terminal.
Who should read this book
This book is intended for CICS terminal operators and persons responsible for preparing
terminal operating procedures. It is also useful for both system and application programmers.
What you need to know to understand this book
A general knowledge of the concepts and terminology is required.
How to use this book
This book is mainly for reference. After a short introduction, the rest of the book is arranged
in alphabetic order of the transaction identifier. An index is provided to pinpoint individual
transactions and keywords.
Some CICS transactions are described in greater detail in other CICS books. These include:
In these cases, this book contains a brief description of the transaction and indicates where
further information is to be found.

Determining if a publication is current
IBM regularly updates its publications with new and changed information. When first
published, both hardcopy and BookManager softcopy versions of a publication are usually in
step. However, due to the time required to print and distribute hardcopy books, the
BookManager version is more likely to have had last-minute changes made to it before
publication.
xii CICS Supplied Transactions
Subsequent updates will probably be available in softcopy before they are available in
hardcopy. This means that at any time from the availability of a release, softcopy versions
should be regarded as the most up-to-date.
For CICS Transaction Server books, these softcopy updates appear regularly on the
Transaction Processing and Data Collection Kit
CD-ROM, SK2T-0730-xx. Each reissue of
the collection kit is indicated by an updated order number suffix (the -xx part). For example,
collection kit SK2T-0730-06 is more up-to-date than SK2T-0730-05. The collection kit is also
clearly dated on the cover.
Updates to the softcopy are clearly marked by revision codes (usually a “#” character) to the
left of the changes.

xvi CICS Supplied Transactions
introduction
Chapter 1. Transactions supplied by CICS
CICS provides operations, usually initiated from terminals,
called
transactions
, each of which involves the use of CICS
tables, programs, and internal services. This book deals with
those transactions that are supplied by CICS and which, in
addition, have an operator interface.
CICS transactions have identification codes that start with “C”
and are 4 characters long; for example, CEMT.
The following table shows the transactions that are described
in this book. For a more complete list of CICS transactions,
including those that do not have an operator interface, see
the Appendix, “List of CICS transactions” on page 263.
In general, you start a CICS transaction by entering its
transaction identifier (for example, CEMT). The transaction
identifier is used by CICS to identify the programs that
handle the specified transactions, and to establish a task to
process them.
If you use an IBM 3270 system display or similar display
device that has the appropriate features installed, you can
also start a transaction by a program function (PF) key or
program attention (PA) key, by an operator identification card
reader, by a magnetic slot reader, or by a light pen. For other
types of terminals or subsystems, see the appropriate
CICS/OS/VS subsystem guide.
Upgrading CICS transactions
You may wish to apply a CICS-supplied upgrade, but are
using modified versions of one or more CICS-supplied
transactions or of the CICS-supplied calling programs that
handle CICS-supplied transactions. After you have first
copied them to differently named groups, you must replace
these private versions from the upgraded CICS-supplied
version and modify them afresh to ensure that the necessary
upgrade changes are carried out. Failure to do this can lead
to unpredictable results.
How to start or stop a transaction
You start a CICS transaction by pressing the CLEAR key to
clear the screen, and entering the transaction identifier, either
by itself or followed by data, on the command line of the
screen. The command line is a single line, usually at the top
of the screen.
You can type the transaction identifier by itself and follow the
prompts until a complete transaction command is built up, or
you can type the complete transaction command on the
command line. If you do not enter enough information, or if
the information you enter is wrong, you are prompted to
complete or correct your input.
For example, in the following transaction, CEMT is the
transaction identifier and the additional data is INQUIRE
PROGRAM(PROG1).
CEMT INQUIRE PROGRAM(PROG1)
When the transaction starts, it processes the additional data.
At the completion of this transaction, you get the following
message:
STATUS: SESSION ENDED
After a transaction has completed, press the CLEAR key to
clear the screen in readiness for the next transaction. You
can cancel any request by typing CANCEL on the command
line.

introduction
Syntax notation and conventions used in
this book
Each command has a syntax box to show you what options
there are.
You interpret the syntax by following the arrows from left to
right. The conventions are:
Minimum abbreviation of keywords
In general, the CICS transactions accept as few characters
of a keyword as needed to identify it within the request. For
example, in a CEMT INQUIRE TASK command, you could
use TASK, TAS, or TA to uniquely identify TASK. T alone,
however, could be confused with TCLASS, TERMINAL,
TRACE, or TRANSACTION.
In the syntax displays on your screen (unless your terminal is
uppercase only), and in most cases in this book, the
minimum permitted abbreviation is given in uppercase
characters, the remainder in lowercase.
Uppercase input to transactions
In general, most CICS-supplied transactions accept only
uppercase input. If UCTRAN=YES has been specified in the
terminal definition, all lowercase characters, even those
enclosed within single quotation marks, are translated to
uppercase.
If you have to specify UCTRAN=NO for your terminal, you
have to ensure that the group specified for your terminal
refers to a profile that will carry out uppercase translation.
CICS provides a PROFILE definition, DFHCICSP, in the
DFHSTAND group in the CICS system definition (CSD) file.
This profile is identical to DFHCICST except that it specifies
UCTRAN(YES) instead of UCTRAN(NO).
The new profile is used by the CICS-supplied page retrieval
transaction, CSPG. The new profile, together with changes in
the task-attach routine and the page retrieval program,
enables CICS to perform uppercase translation at the
transaction level for BMS paging.
This allows users of terminals that are defined with
uppercase translation switched off to use the page retrieval
function without having to enter paging commands in upper
case. Assigning a new profile for CSPG means that all data
entered on the retrieval command (defined by the PGRET
system initialization parameter) and the purge command
(defined by the PGPURGE system initialization parameter) is
translated to uppercase.
If a user’s terminal is defined with UCTRAN(YES), the new
profile has no effect because all terminal input is translated
to uppercase anyway.
Terminal operators
A CICS system makes provision for the following classes of
operators:
A
terminal operator
who can use a terminal to perform
routine transactions that cause application programs to
be processed. You can use a small selection of CICS
transactions. For example, you can inquire about, or
change, the status of your own terminal.
A
supervisory terminal operator
who can perform all the
duties of a terminal operator, in addition to supervising
other operators within a functional group. Your operator
security code gives you access to the supervisory
terminal transaction, CEST, with which you can monitor
and control some of the system resources used by your
group.
A
master terminal operator
who can monitor and control
resources in a CICS system. Your operator security
code gives you access to the master terminal
transaction, CEMT, with which you monitor and control
the system resources. Internal security checking may
limit the range of resources under your control.
