Guh! Now i noticed. You cannot do that in horizontal mode! I mean you
must not fopen() the same file more than once!


If you want to open it with read/write access in text mode without
overwriting it if it exists use:

fp1=fopen(archme, "a+");

if(!fp1)
{
 printf(stderr, "Men the lifeboats. Women and children first!\n");
 return EXIT_FAILURE;
}

...

fclose(fp1);
