TSOer

TSOer is a term that appears in several different contexts to denote a person associated with the acronym TSO. Because TSO can stand for multiple organizations or concepts, the exact meaning of TSOer depends on the setting.

In computing, TSO commonly refers to the Time Sharing Option on IBM mainframe systems. A user who operates within TSO may be informally described as a TSOer, though this usage is not formal and varies by community. TSOers typically work with data sets, submit jobs, and navigate TSO's command environment.

In popular culture, TSO often abbreviates Trans-Siberian Orchestra, a touring rock band. In fan and discussion communities, a person who follows or participates in TSO's performances may be referred to as a TSOer, though this usage is informal and not standardized.

Because TSOer is not a single, standardized term, its meaning should be inferred from context. The term may appear in user-generated content, manuals, or fan discussions, and there is no official registry of who qualifies as a TSOer.
