Introduction

IEBGENER is a utility program in IBM Mainframe systems, particularly under z/OS. It is primarily used for copying and converting data sets, including sequential files, partitioned datasets, and generation data groups.

It can convert and copy sequential file data to PDS members and PDS member data to sequential files. The copy operation can be performed on all types of records having various lengths (including record length > 32760 bytes).

It uses either a sequential file or PDS or PDSE member as input and a new or existing sequential file or a PDS or PDSE member as output.

Usage -

Below is the list of tasks that IEBGENER can perform -

• Copying Data Sets - It can copy one data set to another. It's often used for backing up data, creating duplicates, or moving data from one location to another.
• Creating and Modifying Data Sets - It can create new data sets with specific attributes or modify existing ones, such as changing record formats or lengths.
• Dataset Conversion - Converts between different data set formats, like from fixed to variable length.
• Print Formatting - It can be used to format data for printing.
• Dataset Concatenation - Combines multiple datasets into a single dataset.

Return Codes -

IEBGENER returns a code to specifies the program execution results. The return codes and their meanings are -
