Halting a disk reader *CANCEL,DR
Function
Use the *CANCEL,DR command to halt disk reading immediately. If this command is used to halt a hot reader, the input is halted but is not deactivated unless the KN parameter is included; thus, the *CANCEL command can also be used to change the parameters specified in an *START or *CALL 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.
