Introduction

• IEBCOPY is a dataset utility used to copy or merge members between one or more PDS or PDSEs. The copying can be full or partial.
• IEBCOPY creates a PDS backup and copies 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 of the output PDS.
• IEBCOPY input or output for COPY operation can be a PDS, a PDSE, or an unloaded PS that contains members to be copied, merged, altered, reblocked, loaded, or unloaded.
• IEBCOPY output for COPY operation is either a new or old dataset.

• SYSPRINT - Optional and uses for system output messages.
• SYSOUT - Optional. System-defined DDname for file status codes, system abend codes information, and the display statement output.
• SYSDUMP - Optional. System uses it for dumping when an abend occurs.
• SYSUT01/any-ddname - This is an input DDname and is mandatory. Multiple DD statements can be provided as input.
• SYSUT02/any-ddname - This is an output DDname and is mandatory.
• SYSUT03/SYSUT04 - Optional. These are buffer memory DD statements for processing the task.
• SYSIN - Contains the control statements needed for IEBCOPY utility.
