Compiler Errors

    Compiler errors are generated when a syntax error is encountered in
    the source program file. The first compiler error encountered is
    reported.  At this point, Turbo Pascal enters Edit mode and places the
    cursor on the line where the error was encountered.

    The error messages will be included only if `Y' was entered to the
    prompt `Include error messages (Y/N)?' when Turbo Pascal was first
    started.
