You can use the MODIFY command to cause an external writer to pause
for operator intervention.
F [XWTR.|jobname.]identifier,{PAUSE|P}={FORMS }
{DATASET}
|
The parameters are:
- XWTR
- The name of the IBM-supplied cataloged procedure for the external
writer.
- jobname
- The job name assigned to the external writer.
The job name for a started task depends on
whether the JOBNAME parameter was specified on the START command for
the task:
- If JOBNAME was specified, jobname is the name specified
on the JOBNAME parameter.
- If JOBNAME was not specified and the source
JCL for the started task is a job, jobname is
the name specified on the JCL JOB statement.
- If JOBNAME was not specified and the source
JCL for the started task is a procedure, jobname is
the member name.
You can use
asterisk notation to specify more than one job or started task on
the MODIFY command. See Using asterisks in MODIFY commands for more information.
- identifier
- The identifier of the writer to be modified. (See Displaying started task status for information about determining the job name and
identifier of currently active started tasks.)
The following types
of identifiers can be used:
- The identifier that was specified on the START command.
- [/]devnum, the device number specified on the START or
MOUNT command. A device number is 3 or 4 hexadecimal digits, optionally
preceded by a slash (/). You can precede the device number with a
slash to prevent ambiguity between the device number and a device
type or identifier.
- devicetype, the type of device specified on the START
or MOUNT command.
If no identifier was specified, the identifier “STARTING”
is temporarily assigned until the system can assign another according
to the following order of precedence:
- If an identifier was not specified on the START command, the identifier
is the device type (for example, 3410) or device number (for example,
X‘0000’) specified on the START or MOUNT command.
- If an identifier, a device type, or a device number was not specified
on the START or MOUNT command, the identifier is the device type specified
on an IEFRDER DD statement (invoking a cataloged procedure) in the
JCL.
- If none of the above was specified, the identifier defaults to
the job name.
You can use
asterisk notation to specify more than one job or started task on
the MODIFY command. See Using asterisks in MODIFY commands for more information.
- PAUSE= or P=FORMS
- For unit record devices, the writer is to pause when a change
of forms is necessary. The writer stops when it encounters a form
name other than the installation default form name on a SYSOUT DD
statement.
- PAUSE= or P=DATA SET
- For unit record devices, the writer is to pause before starting
to process each data set. When you are ready to continue processing,
you can restart the writer by entering a single character response
to message IEF382A.
Example 1:
To stop writer 00E before it processes each new data set, enter:
F 00E,PAUSE=DATA SET
Example 2:
To stop writer ABCD before it processes each new data set, enter:
F /ABCD,PAUSE=DATA SET
