How can I get an extra segment in DOS?
<p>I'd like to write a little DOS program (my first one) and I'm a little bit inexperienced.</p>

<p>For the program, I need more than 64 kilobytes of (conventional) memory. How can I get extra memory? Ideally, I'd like to have two extra 64k blocks of memory for the program. Can I just start to write data somewhere into the address space or do I need to request extra memory?</p>
