Hi Kalugsky, > Could you explain, please, why the compiler ignores the 'const' in the functiion 'char_const_param(const TStr name)'. There is a huge difference between: char const* char* const Your "const TStr" parameter is a char* const. You need a char const*. Or a char const* const will do, as well. Change your typedef to: typedef char const* TStr; That will give you a char const* const as your parameter. HTH, --Eljay
