COPYMOD

• COPYMOD statement used to copy load module libraries that need to reblock.
• The output data set should be PDS.
• The input data set may be a PDS or a PS created by an unload operation.

Syntax -

//SYSIN     DD  *
  	[label] COPYMOD OUTDD=DDname,INDD={DDname|((DDname,R))} 
		[,MAXBLK={nnnnn|nnK}]
		[,MINBLK={nnnnn|nnK}] 
		[,LIST={YES|NO}]
/*

• OUTDD=DDname - Specifies the DDname of the output PDS.
• INDD=[(]{DDname|(DDname,R) }[,...][)] - Specifies the DDname of the input PDS.
• R - Specifies that the members to be copied or loaded from the input data set will 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 a decimal number.
  nnK tells that the nn value is to be multiplied by 1024 bytes. MAXBLK can be coded 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.
  nnK means that the nn value is to be multiplied by 1024 bytes. MINBLK can be coded with or without MAXBLK.
• LIST={YES|NO} - Specifies that the altered member names to be listed in the SYSPRINT data set. When ignored, the default listing option from the EXEC PARM gets applied.

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.
