debugger by typing in

, you should see a display similar to this one (it
may not be exactly the same, but it should be close).

Key features of the debugger
-
Easy-to-use, window-oriented interface. The DSK debugger separates
code, data, and commands into manageable portions.
-
Powerful command set. Unlike many other debugging systems, this de-
bugger doesn’t force you to learn a large, intricate command set. The DSK
debugger supports a small, but powerful, command set.
-
Flexible command entry. There are two main ways to enter commands.
You can enter commands at the command line or use the function keys;
choose the method that you like better.
