Use the START XWTR command to start an external writer.
S {XWTR|membername}[.identifier][,devicetype|,[/]devnum]
[,volumeserial][,classes][,keyword=option[,keyword=option]...]
The parameters are:
XWTR
The name of the IBM-supplied cataloged procedure that invokes
the external writer.
membername
The name of the member that contains the source JCL that starts
and defines the external writer. The member can contain a cataloged
procedure (for example, residing in SYS1.PROCLIB) or a job residing
in a partitioned data set. The name can be either the IBM-assigned
name (XWTR) or a user-assigned name.
identifier
The identifier of the writer to be started. This name consists
of up to eight characters. The first one must be alphabetical. If
you do not assign an identifier, the system uses the device number
of the device allocated to the writer as the identifier.
devicetype
The device type, such as 3211, of the writer to be started.
Note:devicetype and devnum are mutually exclusive.
[/]devnum
The device number of the writer to be started. A device number
is 3 or 4 hexadecimal digits. A slash (/) must precede a 4-digit
number and is optional before a 3-digit number.
Note:devicetype and devnum are
mutually exclusive.
volumeserial
The serial number, up to six characters, of the magnetic tape
or direct access volume the writer is to use.
classes
The output classes, in priority sequence, the writer is to process.
You can specify up to eight output classes, naming them in sequence
without separating them by commas.
keyword=option
Any appropriate keyword specified to override the corresponding
keyword in the cataloged procedure. The maximum length of each keyword=option
is 66 characters. No individual value within this field may be longer
than 44 characters in length. If you are overriding a symbolic parameter,
do not use any of the DD keywords. For example, do not use UNIT=
to override the devicetype positional parameter in the cataloged procedure.
Example:
To start an external writer with the identifier A, enter:
