Indicates the beginning of a copy and load module reblock operation. COPYMOD statement used to copy load module libraries that to reblock.

The output data set must be partitioned. The input data set may be a partitioned or a sequential data set created by an unload operation.

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.

MAXBLK={nnnnn|nnK}

specifies the maximum block size for records in the output PDS. The nnnnn value is specified as a decimal number;

K

K indicates that the nn value is to be multiplied by 1024 bytes. MAXBLK may be specified with or without MINBLK.

MINBLK={nnnnn|nnK}

specifies the minimum block size for records in the output PDS. The nnnnn value is specified as a decimal number;

K indicates that the nn value is to be multiplied by 1024 bytes. MINBLK may be specified with or without MAXBLK.

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.

//STEP1    EXEC PGM=IEBCOPY
  //REPLACE  JOB  ...
  //SYSPRINT DD  SYSOUT=A
  //TESTLIB  DD  DSN=TEST.LOADLIB,DISP=SHR,UNIT=3390,
  //             VOL=SER=TEST01
  //PRODLIB  DD  DSN=PROD.LOADLIB,DISP=(OLD,KEEP)
  //             UNIT=3380,VOL=SER=PROD01
  //SYSIN    DD  *
             COPYMOD OUTDD=PRODLIB,INDD=TESTLIB
             SELECT MEMBER=((NEWPROG,,R))
  /*

Let’s discuss the example in detail.

• TESTLIB, PRODLIB DD defines a load library.
• SYSIN DD defines the instream control data set.
• The COPYMOD statement identifies PROD.LOADLIB as the output data set and TEST.LOADLIB as the input data set.
• The SELECT statement indicates the load module NEWPROG is to be copied from the input data set with replace if already exists.
