How using ROM BIOS interrupts in borland c++ 5.02?
<p>I am using Borland C++ 5.02 and I was trying to make ROM BIOS interrupts in a c++ program. (i use REGS &amp; regs). But when I compile the program it says undefined structure REGS(for all interrupts).</p>

<pre><code>int numlock() {
    union REGS in,out;
    in.h.ah=2;
    int86(0x16,&amp;in,&amp;out);
    return out.h.al;
}
union REGS in,out;  //**error line**   
</code></pre>
