How to use strings in emu8086
<p>I need help with strings in emu8086. I have initialized a string:</p>

<pre><code>str1 db "0neWord"
</code></pre>

<p>And I have an empty string:</p>

<pre><code>str2 db ?
</code></pre>

<p>Now I need to check all letters in <code>str1</code> and copy to <code>str2</code>, but if the letter in <code>str1</code> is 0, I need to replace it with O. If not, I need to just copy the letter.</p>

<p>How can I do this?</p>
