introduction
messages from other terminals and consoles, as well as from
CICS transactions.
In a system that has consoles and VTAM terminals, a
console can remain active when CICS and VTAM are
disconnected from each other. You can use the console to
make or break the CICS-VTAM connection without CICS
being terminated.
Use the MODIFY and REPLY commands to start the
CICS-supplied transactions from an operating system
console.
In addition to the MODIFY and REPLY commands, the
system programmer should consider use of the CONTROL,
DISPLAY, START, and VARY commands when preparing
console operator procedures. For information on these
commands and other system details, see the
OS/390 MVS
System Commands
manual.
Rules for console entry
Commands typed at a console are translated to uppercase,
except for characters enclosed within single quotation marks
(''), which remain unchanged. The occurrence of a literal
single quotation mark must be indicated by a pair of single
quotation marks (''), for example:
'Please phone Mr O''Neill'.
If UCTRAN=YES has been specified in the terminal
definition, all lowercase characters, even those enclosed
within single quotation marks, are translated to uppercase.
MODIFY command
You start a CICS transaction from a console by using the
MODIFY command, as follows:
MODIFY ident,datastring
You can abbreviate the MODIFY command to F.
ident can be any of the following:
The name of the job used to start CICS, when it is
started by a job stream.
The name of the procedure used to start CICS, when it
is started by an MVS START command, for example:
START procedure_name
where “procedure_name” is the ident value.
The task identifier that was used to qualify the procedure
name, for example:
START procedure_name.taskid
where “taskid” is the ident value. This is likely to be used
where the same procedure is started more than once.
datastring is a string of data, starting with a CICS
transaction identifier.
For example, to start transaction CEBT on the CICSA system
from the console, type:
MODIFY CICSA,CEBT PERFORM TAKEOVER
You can type more than one MODIFY command at a
console; each is processed in order of entry.
A CICS transaction can issue terminal control READ,
WRITE, or CONVERSE commands to communicate with a
console operator. WRITE and CONVERSE transmit
application program messages, but READ simply produces a
prompt, incorporating message ‘DFH4200A’, as follows:
@nn DFH42A jjjjjjjj tttt
where:
nn is the number (generated by the operating
system) that you must use in your reply to the
prompt. Messages from a transaction that uses
CONVERSE commands also contain this
number.
jjjjjjjj is the jobname of CICS in the operating system.
tttt is the transaction identifier of the CICS
transaction that has issued the READ command.
REPLY command
You (the console operator) must respond to each prompt by
using the REPLY command, which you can type at either the
prompted console or the master console:
R[EPLY] nn,datastring
