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.
