I am seeing the retention period of a dataset as 0. Is that because this is a VSAM dataset. If it is a VSAM dataset how will I find its retention perdiod.

What does it mean if the retention period of a dataset shows as 0?

A mainframe operating system is networking software infrastructure that allows a mainframe computer to run programs, connect linked machines, and process complex numerical and data-driven tasks. Modern mainframe design is generally defined by redundant internal engineering, extensive input-output facilities, strict backward compatibility with older software, high hardware and computational utilization rates and high stability and reliability. Well-known operating systems include IBM z/OS, z/VM, zTPF, z/VSE, OS/390, and their predecessors, along with MCP for Unisys ClearPath, and NonStop OS/Guardian on HP/Tandem, and questions regarding the IBM midrange operating system called IBM i, OS/400, and i5/OS.
