6. Verify that the input area command byte was cleared during
initialization.
Type:
U> m -db 0ff800
You will see:
00ff800..00ff800 00
The input byte location was successfully cleared.
7. Now we will use the emulator features to make the program
work. Remember that the program writes specific messages to
the output area depending on what the input byte location
contains. Type:
U> m 0ff800=41
This modifies the input byte location to the hex value for an
ASCII "A". Now let’s check the output area for a message.
U> m 0ff804..0ff823
You will see:
00ff804..00ff813 54 48 49 53 20 49 53 20 4d 45 53 53 41 47 45 20
00ff814..00ff823 41 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
These are the ASCII values for Msg_A.
Repeat the last two commands twice. The first time, use 42
instead of 41 at location ff800h and note that Msg_B
overwrites Msg_A. Then try these again, using any number
except 00, 41, or 42 and note that the Msg_I message is
written to this area.
