Sta Current thread state:
Bl = The thread is blocked waiting for timer expiration,
resources, or a synchronization event.
Io = A DUP local program is blocked waiting for terminal
I/O completion.
Rn = The thread is currently executable.
CPU% Shows the percentage of execution time credited to each thread since
the last screen update. The values might not total 100% due to
rounding errors and display limitations. An unexpected amount of
time can be credited to some threads because the controller firmware
architecture allows code from one thread to execute in the context of
another thread without a context switch.
