Introduction

• IEBCOPY is a data set utility used to copy or merge members between one or more PDS or PDSEs. The copying can be full or partial.
• IEBCOPY is used to create a PDS backup and copy members from the backup into a PDS.
• IEBCOPY automatically lists the number of unused directory blocks.
• IEBCOPY lists the number of unused tracks available for members if the output data set is a PDS.
• IEBCOPY input for copy operation can be a PDS, a PDSE, or unload data set that contains members to be copied, merged, altered, reblocked, loaded, or unloaded.
• IEBCOPY output for copy operation can be an Output data set. The output data set is either a new or old data set.

• SYSPRINT - This is an optional DD statement. Utility programs use it for their output.
• SYSOUT - This is an optional DD statement. SYSOUT specifies a system-defined DD name for file status codes, system abend codes information, and the display statement output.
• SYSDUMP - This is an optional DD statement. The system uses it for dumping when an abend occurs.
• SYSUT01/any-ddname - This is an input DD statement and is mandatory. Multiple DD statements can be provided as input.
• SYSUT02/any-ddname - This is an output DD statement and is mandatory.
• SYSUT03/SYSUT04 - These are buffer memory DD statements for processing the task. These are optional.
• SYSIN - Contains the control statements for processing the task.
