It helps if you can ask a more specific question. When you simply "I do not understand" it's hard for us to do anything other than to repeat the text. Please try to say what it is that you do not understand. In the C and C++ standards, the type "char" can be either signed or unsigned. GCC picks a default setting which works well for the processor. This option overrides the default setting to say that "char" is unsigned. Ian
