title: How to create a ms-dos 7.10 program?
body: <p>In times to times I see at stores some sellers' programs made in MS-DOS. The program is just black and white, the usage is basically by keyboard. It is not the command prompt because it seems to have a 3D visual, something can be clicked by the mouse, what in cmd doesn't happen.</p>
  
  <p>Below I put two images that show those program I said:</p>

  <p>So my questions are:</p>
  
  <ol>
  <li>What OS the computer use to operate a program like that.</li>
  <li>How can I make a program like that, what software I need and what language I need to know?</li>
