TNS Program Example
Resuming gives us these outputs:

Note. There is already some text in the data area of the first breakpoint. This procedure is
reusing some of the data area the EXAMPLE_INIT procedure used in previous examples.
Thus, if we had entered our breakpoint at the beginning of the program as "bm n 0x32, w," we
would have stopped in the EXAMPLE_INIT and EXAMPLE_FILL_ARRAY procedures.
