//COPY JOB ,'your name',CLASS=class,TIME=(mm,ss),LINES=lines 
/*ROUTE  PRINT node.location                                 
// EXEC PGM=IDCAMS                                           
//SYSPRINT DD SYSOUT=A                                       
//indd  DD DSN= ... (describes the input data set)           
//outdd DD DSN= ... (describes the output data set)          
//SYSIN DD *                                                 
REPRO -                                                      
  INFILE(indd) -                                             
  OUTFILE(outdd)  NOREPLACE

//DELETE JOB (acctg info),CLASS=class.MSGCLASS=class,NOTIFY=your userid 
//DELETE EXEC PGM=IDCAMS                                    
//SYSPRINT DD SYSOUT=*                                      
//SYSIN DD *                                                
 DELETE (dataset name)                       
 IF LASTCC EQ 8 THEN SET MAXCC=0
