CECI/CECS—command-level interpreter
Chapter 8. CECI—command-level interpreter
Use CECI, which invokes the CICS command-level
interpreter, to enter an EXEC CICS command, check its
syntax, and modify it if necessary. In most cases, you can
also process the command.
For programming information on each EXEC CICS
command, see the
CICS Application Programming Reference
manual or the CICS System Programming Reference
manual.
For details of how to use the CECI transaction, see the CICS
Application Programming Guide, which includes an example
of a complete session with CECI.
Start the transaction by entering CECI on the command line
of the screen, as follows:
CECI
Press ENTER. You get a list of all EXEC CICS commands.

Note: RECEIVE and SEND cannot be used on
TCAM-attached terminals. If you then enter the
command or its abbreviation on the top line and
press ENTER, you get a complete display of the
syntax for that command. For example, Figure 17
shows the screen displayed for the EXEC CICS
RETRIEVE command.

Figure 17. CECI transaction: RETRieve command screen
Alternatively, you can enter CECI together with the name of
the command in which you are interested, and bypass the
full list of commands; for example:
CECI asktime
In both cases, you can generally go on to check the syntax
of the command, change it if necessary, and then process
the command.
Many CICS system programming commands use CVDA
values, and CECI shows numeric equivalents for these. See
the
CICS System Programming Reference manual for
programming information, including a “translation” of these
numeric values to their alphabetic values.
The HELP panel
If you press the help key (PF1), the following panel is
displayed:
GENERAL HELP INFORMATION
Enter command on the first line and press ENTER (after returning from HELP).
Options can be abbreviated to the minimum to make them unique.
? before command gives COMMAND SYNTAX CHECK and prevents execution.
To expand a value or variable to full screen,
