Because of the way that tasks can block, their lifecycle is much more complex than other threads.  Each task instance maintains a state to track what their current status is at any given moment of time, and the BIOS scheduler maintains and updates each task’s status throughout the life span of the application. Any tasks that are created statically will be set up and made ready to run when the SYS/BIOS scheduler starts. Of course, if a task is created dynamically later, it will not reach the READY state until that time.
