It is also called as task control block.Open task control blocks (open TCBs) The open transaction environment (OTE) is an environment where threadsafe application code can run on its own TCB inside the CICS® address space, without interference from other transactions. Applications that use the OTE can run on a class of TCB called an open TCB, or on the quasi-reentrant TCB (QR TCB).A task control block (TCB) represents a z/OS task. A running CICS system is a z/OS address space containing multiple TCBs and hence multiple z/OS tasks. Within CICS, a CICS task itself runs on a TCB. Before the open transaction environment (OTE) was implemented in CICS, CICS used a single TCB to run all user …The process control block typically contains: An ID number that identifies the process. Pointers to the locations in the program and its data where processing last occurred. Register contents. States of various flags and switches.

Each task has its own context, which is the CPU environment and system resources that the task sees each time it is scheduled to run by the kernel. On a context switch, a task’s context is saved in the task control block (TCB). A task’s context includes: a thread of execution; that is, the task’s program counter.In single-task blocks of the dual-task part, an asterisk, which served as task-irrelevant S1, appeared to the left of the fixation cross, followed by a task-relevant S2 to the right of the fixation cross after a random SOA of 100 ms or 600 ms. In dual-task blocks, the asterisk was replaced by a task-relevant S1.1. Neither of those terms ("Process Control Block" or "Process Descriptor") are considered "terms of art" in Linux kernel development.
