Task control block.
Handling errors with blocks. You can control how Ansible responds to task errors using blocks with rescue and always sections. Rescue blocks specify tasks to run when an earlier task in a block fails. This approach is similar to exception handling in many programming languages. Ansible only runs rescue blocks after a task returns a ‘failed ...

Bootstrap program is a program which runs initially when the system or computer is booted or rebooted. Process Control Block (PCB, also called Task Controlling Block, [1] Task Struct, or Switchframe) is a data structure in the operating system kernel containing the information needed to manage a particular process. The PCB is "the manifestation of a process in an operating system. and its duty is: Process identification data.
A task can exist in one of the following states: Running. When a task is actually executing it is said to be in the Running state. It is currently utilising the processor. If the processor on which the RTOS is running only has a single core then there can only be one task in the Running state at any given time. Ready.

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).Organize tasks into Task Control Blocks (TCBs, a.k.a. Process Control Blocks) !
