Abstract
TASID is a full-screen system information display and much more.
Download Description
Use the TASID system monitor to view system activity on a z/OS® system. This information includes active address spaces (batch jobs, started tasks, TSO users, and system tasks), ENQ activity and contention, initiator status on JES2 systems, and so on.
Note: some options might not behave consistently or operate correctly on every level of z/OS. All available documentation is contained in the help panels, which you can access by pressing the HELP function key when on any panel within TASID.
This tool is available on an "AS IS" basis.

Unsupported level TASID could not find the PIT control block.
