Parameters

The parameters for this command are:

jobname
The name of the batch job, started task, or APPC/MVS transaction program to be modified.
The job name for a given started task can be assigned based on a variety of inputs. These inputs are examined in the following order, so that if item #1 is not specified, item #2 is used. If neither #1 nor #2 is specified, then #3 is used, and so on.
  1. The jobname specified in the JOBNAME= parameter of the START command

    or

    The specified on the START command.

  2. The jobname specified on the JOB JCL statement within the member.
  3. The device number specified on the START command, or the device number associated with the device type specified on the START command

    or

    The device number associated with the device type specified on the START command.

  4. The device number associated with the IEFRDER DD statement within the member.
  5. 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 assigned to the job or started task. (See Displaying started task status for information about determining the jobname and identifier of currently active started tasks.)
Use one of the following types of identifiers:
  • The identifier that was specified on the START command.
  • [/]devnum, the 3-digit or 4-digit hexadecimal device number specified when the START or MOUNT command was issued.

    When you specify a device number that could be mistaken for the device name, precede the device number with a slash. The slash is optional with a 3-digit device number.

  • devicetype, the type of device specified when the START or MOUNT command was issued.
If no identifier was specified, the identifier “STARTING” is temporarily assigned until the system can assign another according to the following order of precedence:
  1. 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.
  2. 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 catalogued procedure) in the JCL.
  3. 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.

parameters
Program parameters passed to the started program.

Example 1:

If the program currently running in job TMASGX02 was set up by the programmer to accept 2-digit values from the operator, enter the following (where nn is an appropriate 2-digit value): 
f tmasgx02,nn

Example 2:

If started tasks are running with the following jobnames and identifiers: 
Jobname = ABC1, identifier = DEF1
Jobname = ABC2, identifier = DEF2
And both tasks accept the value “INPUT1” from the operator, enter: 
f ABC*.DEF*,INPUT1

Both tasks receive the value INPUT1.
