Hello,

I need to print a string which was returned to me by vesa routine
00h.
What I did didn't work:

----- BEGIN OF BUGGY PROGRAM ----------------
typedef struct
{
  short offset,
        segment;
} Toldptr;

Toldptr return;

string=(char *)return.segment*16+return.offset;
printf("%s\n",string);
----- END OF BUGGY PROGRAM ----------------

----- BEGIN OF WORKING, BUT BAD STYLE PROGRAM ------
typedef struct
{
  short offset,
        segment;
} Toldptr;

char    string[1000];
Toldptr return;
dosmemcpy(return.segment*16+return.offset,1000,string);
prinf("%s\n",string);
----- END OF WORKING, BUT BAD STYLE PROGRAM ------

Maybe the upper one is stupid, but seems obvious for me.

What did I do wrong? I would like to find out, because the string
is zero terminated and not necessarily up to 1000 chars long.

Thanks for any help

Mirko
