! **** Warning ... if the task block fields are changed, they
! **** must also be changed in the files NMUT20.MAC, NMUT10.MAC,
! **** NMUMCB.MAC.

! Note that the TB_SCHED_QUEUE field is used to enter the task
! block onto the RUN_QUEUE, any EVENT_QUEUE and the TIME_QUEUE.
! Since each queue is mutually exclusive, there is no conflict.
