/////////////////////////////////////////////////////////////////////////////
// Descripton: The Debug() member function writes a message to the screen
// and/or the log file. The requested debug-level, the 'level' parameter is
// checked against the level retrieved from the ini-file during start of the
// task
// Internally the fl_xlate function is used to convert from a key-string to a
// language dependent message. The function accepts variable number of
// parameters. The format of these parameters must be consistent with the
// format in the language tranlsation file.
//
// Parameters: codetracetext - text to log, casn include format specifiers.
// level - required debug level neede to log this message.
// event - log indication for eventviewer: EVENTLOG_SUCCESS, EVENTLOG_INFORMATION_TYPE
// or EVENTLOG_WARNING_TYPE.
// type - type of message: TRACE_TEXT, TRACE_START or TRACE_STOP. Message will
// indicate  normal text (if given binairy data is included), or starting or
// stopping.
// bin - binaire data, e.g. rx or tx data of a driver.
// binlen - legth of binairy buffer.
//
// Returns:
//
// Comment:
