display memory Cmd_Input bytes to 41h
run trace
The sample program simulates a primitive command interpreter.
Commands are sent to the sample program through a byte sized
memory location labeled Cmd_Input. You can use the modify
memory feature to send a command to the sample program. For
example, to enter the command "A" (41 hex), use the following
command.
modify memory Cmd_Input bytes to 41h <RETURN>
Or:
modify memory Cmd_Input string to 'A'
<RETURN>
(Single character strings are allowed in expressions.)
As you can see, the memory display is automatically updated, and
shows that the "THIS IS MESSAGE A" message is written to the
destination locations.
