Indicates the beginning of a COPYGROUP operation. COPYGROUP statement used to begin a group copy, unload, or load.

A group consists members and its aliases. COPYGROUP treats the group as a single entity.

OUTDD=DDname

specifies the output DD statement dataset name.

INDD=[(]{DDname| (DDname,R)}[,...][)]

specifies the input DD statement dataset names.

R

specifies that the members to be copied or loaded from input data set are to replace any identically named members on the output PDS.

LIST={YES|NO}

specifies names of the copied members are to be listed in the SYSPRINT data set. When ignored, the default from the EXEC PARM will be applied

Members and their aliases are copied from a PDSE to a PDSE.

//CPYGROUP  JOB  ...
  //STEP1     EXEC PGM=IEBCOPY
  //SYSPRINT  DD  SYSOUT=A
  //DDIN      DD  DSNAME=PDSESETA,DISP=SHR
  //DDOUT     DD  DSNAME=PDSESETB,LIKE=PDSESETA,DSNTYPE=LIBRARY,
  //              DISP=(NEW,CATLG)
  //SYSUT3    DD  UNIT=SYSDA,SPACE=(TRK,(1,1))
  //SYSIN     DD  *
  	GROUPCPY   COPYGROUP  INDD=DDIN,OUTDD=DDOUT
  /*

Let’s discuss the example in detail.

• PDSESETA,PDSESETB is a partitioned data set extended.
• SYSUT3 DD defines a temporary data set.
• SYSIN DD defines the instream control data set
• COPYGROUP indicates the start of the copy operation.
