No, any additional info is very welcome. Both, pointers and the whole subject of memory, is very hard for me, in general.

Reading the FAQ about name[3] and *name i think this: I am quite sure that i read somewhere (K&R?) that the compiler immediatly translates the one to the other ( i think indexed to pointers). All i can find in my book is this: "There is one difference between and array name and a pointer that must be kept in mind. A pointer is a variable, pa=a and pa++ are legal. But an array name is not a variable; constructions like a=pa and a++ are illegal"

I am not sure, but i think what i wrote above, that list++ gives me an lvalue error, is related? After Don's explanation: In your program, list is the address where an array of pointers to characters is stored. The statement: list++ would be an attempt to move that array to a new location in memory. Since you can't do that, the C compiler won't allow it."
i seem to be sure, but it won't hurt to ask if i am right.

side note: I am never sure about the right terminology. Please correct me if i use terms wrong.

mlm

FBB::mlm(3bobcat)                                             OFoldStream manipulator                                            FBB::mlm(3bobcat)

NAME

       FBB::mlm - Manipulator modifying left margins of OFoldStream objects

SYNOPSIS

       #include <bobcat/ofoldstream> or
       #include <bobcat/ofoldstreambuf>
       Linking option: -lbobcat

DESCRIPTION

       The  mlm  class  implements  a  manipulator that can be inserted into OFoldStream objects to modify the stream's left margin by a requested
       amount. The request cannot result in a negative left margin value. If a negative left margin would be the arithmetic result of the  request
       then left margin 0 will silently be used.

       Depending  on  the  tab-setting  of  the  OFoldStream  the  inserted value represents the number of blank space characters or the number of
       tab-characters that will be added to the left margin.

       The request will be processed at the next newline character or std::flush or std::endl manipulator that is inserted into the stream.  If  a
       line  is  still empty once an mlm object and a flush manipulator are inserted into the stream then the new left margin will be effective at
       the next word inserted into that line (cf., the example section below)

       A bad_cast exception is thrown when the manipulator is inserted into an ostream that is not using a OFoldStreambuf buffer.

           int main()
           {
               OFoldStream out(cout, 0, 80);
               out << "hello world (left margin is 0)" << mlm(4) << "
"
                      "this uses a 4 character wide left margin
" <<
                       mlm(-10) << flush <<
                       "left margin -6 changed to 0, active on this line
";
               return 0;
           }
