Purpose: Use the MODIFY command to pass information to a job or started task. Note that you can communicate with a currently running program only if it was designed to recognize input from the MODIFY command. If the program does not recognize the input specified on the MODIFY command, MVS issues message IEE342I MODIFY

F [jobname.]identifier,{USERMAX=nnnnn}
{USER={SIC } }
{ {FSTOP} }

Parameters

The parameters for this command are:

jobname

One of the following:

	The name of a job
	The job name that the system assigns to a started task, which 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" on page 4-271 for more information.

identifier

The identifier assigned to the job or started task.

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:

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.

parameters

Program parameters passed to the started program.
