     CVP.EXE, the protected-mode version of CodeView, has the following
     restrictions:
 
        ■ If you want to switch between the CodeView screen and the
          output screen of the program you are debugging, you must
          use CodeView's F4 key or Screen Exchange (\)
          command. You cannot use the OS/2 Task Manager.
          See: ◄Screen Exchange (\) Command-Window Command►
 
        ■ You cannot debug asynchronously. That is, you cannot execute
          the program you are debugging in one screen group and perform
          other CodeView operations in a second screen group.
 
        ■ To debug a bound program in OS/2 running in the DOS session,
          you must link the program with the OS2.LIB library.
 
        ■ To terminate the program you are debugging, you must type
          CTRL+BREAK or ALT+SYSREQ. CTRL+C does not stop the program.
 
          NOTE: CTRL+C may be used to pass a "break" signal to a
                handler in the program.
 
        ■ Breakpoints in parts of the program that handle messages are
          likely to cause deadlock conditions.
 
        ■ In a multithread program, a thread may not stop at a
          breakpoint if all threads are in a critical section of
          Presentation Manager code.
