Let's not pass up the opportunity to observe that TSO is not 'time sharing', nor is it 'optional', yet it's constantly on the lips of every mainframer. I caution newbies (and managers and auditors) not to give much weight to these acronyms. Saying 'multiple virtual storage' more than once in a meeting marks you as a doofus. ;-)

There is an address space for each batch job, started task, TSO session and similar units of work. Data space: a specialized address space from which instructions are not executed. Subsystem: a body of code identified to MVS as a subsystem and providing service through the subsystem interface. Stated task: a job initiated by the START operator command rather than through the Initiator. In many cases the START is issued automatically shortly after IPL. Started tasks have identifiers starting with S or STC. Job; a unit or work. Batch jobs have identifiers starting with J or JOB. TSO: Time Sharing Option. Support for interactive units of work. Note that you can do Unix System Services work interactively without a TSO session. TSO sessions have identifiers starting with T or TSU. Process: a unit of scheduling for Unix. Depending on how the system is configured, multiple Unix processes may run in a single address space. There may b multiple threads within a process - in fact, the original name for threads as light-weight process. Enclave is a bit difficult describe; take a look at the Language Environment documentation for a start. -- Shmuel (Seymour J.)
