Copying & Reblocking Load Modules

Copying & Reblocking Load Modules

The COPYMOD statement performs copying and reblocks the load modules to the appropriate block size for the target device. The block size of the output PDS is increased by COPYMOD as required to match the MAXBLK value. The maximum block size used by the COPYMOD function is 32760 bytes.

Practical Example -

Scenario - Copying load modules from one PDS to another PDS with different block size.

Explaining Example -

  • SYSUT1 DD DSN=MATEPK.IEBCOPY.INPLOAD - Specifies the input load PDS.
  • SYSUT2 DD DSN=MATEPK.IEBCOPY.OUTLOAD,.. - Specifies the output load PDS.
  • COPYMOD OUTDD=SYSUT2,INDD=SYSUT1,MAXBLK=13030 - Copies members from load members from SYSUT1 to SYSUT2.
