Re: {Spam?} writing binary files

Something like this should work (though is probably not the most 
efficient approach):

   Stdio.File f = Stdio.File("foo.bin", "wct");
   array arr = ({ 4, 5, 9, 12, 255, 0, 8 });
   for(int i = 0; i < sizeof(arr); i++)
     f->write(String.int2char(arr[i]));
   f->close();

   Stdio.read_file("foo.bin");
(2) Result: "\4\5\t\f\377\0\b"


You can probably find a use of sprintf() that can convert the whole int 
array into a string of chars in one go... look at the [] operators in 
the sprintf() documentation.

Hope this helps!
