 Q. When I try to use the any of the pseudo registers, like _AX, I
    get the error message "Undefined symbol '_AX' in function..."
    when I compile. Why?
 A. You are only allowed to use the pseudo registers in the Turbo
    C++ and ANSI modes of the compiler. You can change this setting
    in the Options|Compiler|Source menu.

 Q. Since I don't have a mouse, can I still copy blocks of code
    from one file to another?
 A. Yes. You can mark the beginning and end of a block by moving
    to the appropriate area and pressing Ctrl-K-B (mark beginning) and
    Ctrl-K-K (mark end). You can then use the copy and paste commands
    in the Edit menu.

 Q. The changes I am making using the TCINST utility are not taking effect.
 A. Any options or colors saved directly to TC.EXE using TCINST.EXE may be
    overridden by the contents of a configuration file or a project file.
    When Turbo C++ begins running, it first determines if there is only
    one project file in the current directory.  If there is, this project
    file will automatically be loaded.  Turbo C++ will then look for a
    file with a .tc extension in either the current directory or the
    directory in which the Turbo C++ executable resides, loading it if
    it can be found.

 Q. How do I stop all of the files I have ever edited from constantly
    being open when I bring up Turbo C++?
 A. By default, Turbo C++ saves what is called the desktop configuration.
    This configuration is saved in a file with a .dsk extension. By deleting
    any files of this type then entering Options/Environment /Preferences
    and removing the check from 'auto save desktop', you will begin with a
    clean desktop each time TC is invoked.
