Halting a card reader *CANCEL,CR

Function

Use the *CANCEL,CR command to immediately halt card reading. Cards still in the hopper are not processed. If this command is used to halt a hot reader, the input is halted but the reader is not deactivated unless the KN parameter is included; therefore the *CANCEL command can also be used to change the parameters specified on the *CALL or *START command.

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.

Parameters

CR or devname or devnum or /devnum, or J=jobno

Specifies the reader device to be halted. CR is valid when there is only one card reader. If more than one card reader is currently active, use devname, devnum, /devnum, or jobno to ensure that the proper reader is halted. The device number can be a 3-digit or 4-digit hexadecimal number. A slash (/) preceding the device number is not required. Device numbers can be specified by any of the following formats:

ddd
dddd
/ddd
/dddd

where ddd and dddd represent the device numbers.

H or HN

Specifies that the control-card processor created by the *CANCEL command be placed in hold (H) or allowed to process those jobs already completely entered (HN).

K or KN

Specifies that the hot reader remain allocated (K) or be canceled (KN).

P=nn

Specifies the scheduling priority of the JES3 control-card processor job being canceled. Valid values are 00 through 15.
