SYNTAX            : ARG CTRL_X

RESULTING ARGUMENT: The previous value (meant for use in sequences to be
                    able to change a setting, trap the previous value,
                    and restore it on exit).

FUNCTION          : Log file can be set to ON or OFF.
                    ON    : Extensive debug-information is written
                            to a file while executing commands.
                            The file is named and located similar to TVback,
                            but with '_dbg' appended to the filename.
                            The content of debugging is:
                            - command lists encountered by the parser
                            - individual commands, with their parameters,
                              to be executed
                            - evaluation of expressions
                            - messages to be displayed.
                            - iteration identification
                            - iteration counter
                            So, all parser internal decisions and flow are
                            printed to the debug output-file. This can
                            become a huge amount of data, so it should not
                            be left on all the time. It also makes TV a bit
                            slower in execution. The advantages are that it
                            allows for following the exact path of the
                            parser through a macro. The debug-information
                            is usually more helpful in solving issues in
                            macros than the content of a backup-file.
                    OFF   : No debug-information is logged.

ARGUMENT          : 70: set to ON
                    71: set to OFF

DEFAULT           : OFF
                    TVini may overrule this.

NOTE              : The settings-requester allows comfortable interactive
                    setting of these values on the Amiga.
