Starting a disk reader *START,DR

Function

Use the *START,DR command to restart a hot disk reader when it has reached an EOF condition or to alter or add to the parameters specified when the last *CALL, *START, or *CANCEL command was entered.

If an optional parameter is not specified, the value for that parameter defaults to the value specified on the *CALL command or on the most recent *START or *CANCEL command that modified that parameter.

Parameter

B=nnn

Specifies the size of the job batches created by this reader; that is, the number of jobs to be read from the disk and placed on the spool device. The maximum allowed is 255.

H or HN

Specifies whether the JES3 control-card processor is to be put in the hold state (H) or allowed to process the jobs after the batch has been created (HN).

J=jobname

Specifies the name of the job with which input is to begin.

JOBS=nnn or ALL

Specifies the number of jobs to be read from the input device and placed onto the spool devices. ALL permits reading until a physical EOF is reached. When you specify J=jobname in addition to this parameter, the default for JOBS= is one. The maximum allowed is 254.

K or KN

Specifies whether the designated reader is to be kept active (K) when an EOF condition occurs or is to be allowed to purge (KN). Reading is resumed when you enter an *START command.

M=mem

Specifies the member of the disk reader data set to be read. This parameter is required.

P=nn

Specifies the scheduling priority of the control-card processor job (without affecting the job priorities of the individual jobs being read in). Valid values are 00 to 15.

PARMID=xx

Specifies the set of C/I options to be used for all jobs read in through this reader.
