-During the session, the debugger examines a simple program
-called COUNT. This program counts the letters, words, sentences,

-that will be found and analyzed during the session.
-
-To test the program, a text file called COUNT.TXT is provided.
-The words, sentences, letters, bytes, and other elements in

-During debugging, the numbers in the text file will be compared

-The CodeView demonstration disk is freely copyable. You may

-and use of the demonstration disk.
-
-The debugger on this disk (CVR.EXE) is a restricted version

-
-You control the pace. The session periodically pauses and asks

-are discussed on the screen, you should NOT try to type them.
-The session does this automatically. Just press the SPACEBAR.
-
-You can quit the session after the debugger is started by first 
-pressing CONTROL-C or CONTROL-BREAK, then pressing the SPACEBAR. 
-The word `break' will appear, followed by the CodeView prompt 
-(the greater-than symbol). At the prompt, enter `Q' for Quit.
