Starting 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:

S XWTR.A,282
